UWP group has weird behavior during RunTime

I am new to XAML for UWP. So I am trying to make 4 group boxes using .XAML. When I attempt to run the code it stretches the group box that makes the GUI look terrible. What in the .XAML could cause something like this?
During design time it looks like:
When I run the code in the Simulator it looks like:

Another question I have about UWP applications is do you have to have something special to run the .exe that gets outputted in the Bin folder? When trying to run the .exe as Admin it just crashes and with an unhandled win32 exception.

You used Margin property to control your XAML control's position, it will lead to the messy layout you see.
Please see Layout document to learn how to make a good layouts with XAML in UWP.
For example, you could simply use a Grid control to put these controls on different row and column.
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition></ColumnDefinition>
<ColumnDefinition></ColumnDefinition>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="*"></RowDefinition>
<RowDefinition Height="4*"></RowDefinition>
<RowDefinition Height="4*"></RowDefinition>
<RowDefinition Height="*"></RowDefinition>

Another question I have about UWP applications is do you have to have something special to run the .exe that gets outputted in the Bin folder? When trying to run the .exe as Admin it just crashes and with an unhandled win32 exception.
UWP runs in sandbox, it's different from the classic desktop application. You cannot directly double click the '.exe' file to start it. When you're coding in visual studio, you could press F5 to start it and debug it. If it has been deployed, you could start it from windows 'Start' menu.
Tips: Please do not post multiple question in one post next time.

MaterialDesign- Flipper WPF: Alignment & Scalling is skew.

I'm using the Material Design in a WPF XAML application, I've got this section of code bellow, when the grid is outside of a "materialDesign:Flipper" it all renders correctly; ie- it grows/stretch's correctly with the size of the window and it stacks nicely inside of the StackPanel.
However, as soon as I place this code inside of a Flipper, the scaling and positioning becomes skewed. If I start to change the size of the window it will resize funnily and will not stack nicely. Please see both the image and video bellow for more info. Thank you.
Please note all this code is contained within side a "StackPanel", the intention is such that they can be copied and pasted multiple times.
Working Code outside a Flipper:
<Grid Height="89">
<Grid Width="77" HorizontalAlignment="Left" VerticalAlignment="Center" Margin="7,3,0,2" Panel.ZIndex="2" Height="84">
<Ellipse Fill="{Binding Colour}" HorizontalAlignment="Left" Height="77" StrokeThickness="3" Stroke="#FF464646" Width="77" Effect="{DynamicResource MaterialDesignShadowDepth2}" />
<TextBlock Text="{Binding Name}" VerticalAlignment="Center" HorizontalAlignment="Center" TextAlignment="Center" Width="90" FontSize="{Binding FontSize}" Foreground="White" />
</Grid>
<UniformGrid Rows="2" Columns="1" Panel.ZIndex="3" Margin="89,18,72,0">
<TextBox TextWrapping="Wrap" Text="{Binding BrandName}" FontSize="24" Grid.ColumnSpan="1"/>
<Label Content="Brand Name" Grid.ColumnSpan="1" Grid.RowSpan="2" Margin="-2,-3,2,3"/>
</UniformGrid>
<Button Style="{StaticResource MaterialDesignFloatingActionMiniDarkButton}" HorizontalAlignment="Right" Panel.ZIndex="4" Content="{materialDesign:PackIcon DotsHorizontal}" Command="{x:Static materialDesign:Flipper.FlipCommand}" Margin="0,25,19,24"/>
<materialDesign:Card Margin="24,0,5,5" VerticalAlignment="Bottom" Height="72" Panel.ZIndex="-1" />
</Grid>
Broken Code, inside a Flipper:
<materialDesign:Flipper Visibility="{Binding IsVisible}" Background="#FFE89595" HorizontalAlignment="Stretch">
<materialDesign:Flipper.FrontContent>
Grid Height="89">
<Grid Width="77" HorizontalAlignment="Left" VerticalAlignment="Center" Margin="7,3,0,2" Panel.ZIndex="2" Height="84">
<Ellipse Fill="{Binding Colour}" HorizontalAlignment="Left" Height="77" StrokeThickness="3" Stroke="#FF464646" Width="77" Effect="{DynamicResource MaterialDesignShadowDepth2}" />
<TextBlock Text="{Binding Name}" VerticalAlignment="Center" HorizontalAlignment="Center" TextAlignment="Center" Width="90" FontSize="{Binding FontSize}" Foreground="White" />
</Grid>
<UniformGrid Rows="2" Columns="1" Panel.ZIndex="3" Margin="89,18,72,0">
<TextBox TextWrapping="Wrap" Text="{Binding BrandName}" FontSize="24" Grid.ColumnSpan="1"/>

C# Teststack.White: sometimes unable to find button

I have a WPF application with one window. In that window I have several StackPanels and several Buttons. White can find each Button perfectly, but with exact the same code just one single Button is seldom found and often not found. I was unable to find out what the cause is for this behaviour. Thats why I came to you guys.
Note: Before the buttons are shown, there is another view (in the same window) that waits for the server to respond. As soon as the response is in, the buttons get displayed.
Here my testcode:
[TestMethod]
public void ClickBarPayment_ViewExchanges()
{
DelayedStart(5);
Application app = null;
try
{
app = Application.Launch(SutPath);
try
{
var window = app.GetWindow("CfeMain");
var button = (Button)window.Get(SearchCriteria.ByAutomationId("CashButton"), TimeSpan.FromSeconds(60));
button.Click();
Assert.AreEqual(false, button.Visible);
}
catch (Exception e)
{
Assert.Fail(e.Message);
}
}
finally
{
app?.Close();
}
}
You can assume, that the Buttons are all equal and all have a Tag " Name="" ". Here is the XAML code, I remove unnecessary names with "Blabla" a.s.o.
<StackPanel Name="PaymentContent" Visibility="Visible" VerticalAlignment="Center" Margin="0,0,0,0">
<StackPanel Height="60" VerticalAlignment="top" Margin="20,0,10,0">
<TextBlock FontSize="24" Foreground="#0b0b0b" Name="info" HorizontalAlignment="Stretch">Bla</TextBlock>
</StackPanel>
<StackPanel Name="options" Orientation="Vertical" HorizontalAlignment="Center" Grid.RowSpan="2" Width="1004">
<StackPanel Orientation="Horizontal" HorizontalAlignment="Center" Margin="5,15,5,0">
...
...
</StackPanel>
<StackPanel Orientation="Horizontal" HorizontalAlignment="Center" Margin="5,0,5,5">
<Button Name="Blablabla" Click="Blablabl_OnClick" Style="{StaticResource MainButtonBottomLeft}" Background="#efefef" Margin="0,10,10,0" HorizontalAlignment="Center" Width="490" Height="200">
<StackPanel Orientation="Vertical" HorizontalAlignment="Left" Width="400" Height="200">
<TextBlock FontSize="28" Height="40" Margin="0,10,0,0" Name="BlablaText">Bla</TextBlock>
<TextBlock FontSize="18" Height="30" Name="BlablaInfo"/>

<StackPanel Name="BlablablIssuer" Height="100" Orientation="Horizontal">
<Image Source="/Images/Blasdsd.png" Width="95" Height="35" />
</StackPanel>
</StackPanel>
</Button>
<Button Name="CashButton" Click="Cash_OnClick" Style="{StaticResource MainButtonBottomRight}" Background="#efefef" Margin="0,10,0,0" HorizontalAlignment="Center" Width="490" Height="200">
<StackPanel Orientation="Vertical" HorizontalAlignment="Left" Width="400" Height="200">
<TextBlock FontSize="28" Height="40" Margin="0,10,0,0" Name="NoteText">Bla</TextBlock>
<TextBlock FontSize="18" Height="30" Name="NoteInfo"><Run Text="Schweizer Franken Banknoten"/></TextBlock>
<Separator Style="{StaticResource {x:Static ToolBar.SeparatorStyleKey}}" Background="#859fcd" Margin="0,10,0,0" Width="460" />
<StackPanel Name="noteIssuer" Height="100" Orientation="Horizontal">
<Image Source="/Images/100frank.jpg" Width="85" Height="55" Margin="0,0,5,0"/>
<Image Source="/Images/50frank.jpg" Width="80" Height="55" Margin="0,0,5,0" />
<Image Source="/Images/20frank.jpg" Width="80" Height="55" Margin="0,0,5,0" />
<Image Source="/Images/10frank.jpg" Width="75" Height="55" Margin="0,0,0,0" />
<Image Source="/Images/qrCode.png" Width="51" Height="45" Margin="0,28" />
</StackPanel>
</StackPanel>
</Button>
</StackPanel>
</StackPanel>
</StackPanel>

Without actually facing the issue I can make only suggestions.
Potential reason could be that window object getting initialized prior to having all buttons enabled in actual Application window.
You could add a wait time prior to initialize window

Problems Binding with a GridView UWP

I have a Binding page for some bugs and another one for comments in my app. The first one work properly, but the second one don't show anything but the data(21 comments) load successfully.
I've been taking a look to the live Live Property Explorer and the first Grid have those options:
However, the second one have the ItemsSource set as null:
This should not be possible, because those items have the same code just with few changes to make them load different.
Here you have the code:
<Page.Resources>
<DataTemplate x:DataType="data:Book" x:Key="BookDataTemplate">
<StackPanel HorizontalAlignment="Center">
<Image Width="150" Height="150" Source="{x:Bind CoverImage}" />
<StackPanel HorizontalAlignment="center" Orientation="Horizontal">
<TextBlock FontSize="10" Text="{x:Bind DScore}" HorizontalAlignment="Center" Foreground="#FF21C721" />

</StackPanel>
<TextBlock FontSize="16" Text="{x:Bind Title}" HorizontalAlignment="Center" Foreground="White" />
<TextBlock FontSize="10" Text="{x:Bind Author}" HorizontalAlignment="Center" Foreground="#FF9C9C9C" />
<ToolTipService.ToolTip>
<TextBlock Text="{x:Bind DData}"/>
</ToolTipService.ToolTip>
</StackPanel>
</DataTemplate>
</Page.Resources>

And the Comments gridview:
<Page.Resources>
<DataTemplate x:DataType="data:Comment" x:Key="CommentDataTemplate">
<StackPanel HorizontalAlignment="Center">
<Grid>
<Rectangle Margin="50, 0, 0, 30" Fill="#FF144772" Height="100" Stroke="Black" Width="500" HorizontalAlignment="Center"/>

<Image x:Name="image" HorizontalAlignment="Left" Height="50" Margin="65,18,0,0" VerticalAlignment="Top" Width="50" Source="Assets/profile.png"/>
<StackPanel HorizontalAlignment="center" Orientation="Horizontal">

<ToolTipService.ToolTip>
<TextBlock Text="{x:Bind Score}"/>
</ToolTipService.ToolTip>
</Grid>
</StackPanel>
</DataTemplate>
</Page.Resources>
<GridView ItemsSource="{x:Bind Comments}" AllowDrop="True" IsSwipeEnabled="True" IsItemClickEnabled="True" Name="Content" Margin="0,100,0,40" CanReorderItems="True"
CanDragItems="True"
ItemTemplate="{StaticResource CommentDataTemplate}" ReorderMode="Enabled"/>
Can somebody help me identify the problem here please?

In the XAML file of your 2nd page go to "Comments" in ItemsSource and press F12. If you could navigate to definition of Comments means your binding is successful but Comments is not getting populated. If you could not navigate to definition means binding is not working. In that case check if datacontext has been set for that page. Also check how "Comments" is spelled in XAML and in the property.
