HorizontalStackLayout size issue

[kj4bix]

I have an issue that would seem to be very simple. I have a vertical stack layout that has a list of horizontal stack layouts inside. I have the first item in the horizontal stack layout set at the Start and the 2nd at the end, but even though the HorizontalStackLayout fills the page, the second control doesn't move to the end.

Has anyone else had this same issue? I'm running on Windows since is it the quickest, didn't look at the other environments. My iOS environment is basically broken since the update to 17.7.4 - connection issues to the Mac.

Here is my XAML - which seems to be rather simple and an image of the result. You can see the red background which is correct, but the second item in the horizontal stack layout ignores the HorizontalOptions="End".

<StackLayout Margin="20, 10, 20, 10" Orientation="Vertical" HorizontalOptions="FillAndExpand">

    <HorizontalStackLayout Margin="0, 10, 0, 10" BackgroundColor="Red" HorizontalOptions="FillAndExpand">
        <Label Margin="0, 10, 20, 10" HorizontalOptions="Start" FontSize="{StaticResource MediumFont}" FontAttributes="Bold" Text="Package #22J"/>
        <Label Margin="0, 10, 0, 0" HorizontalOptions="End" FontSize="{StaticResource MediumFont}" FontAttributes="Bold" Text="Phase 1" />
    </HorizontalStackLayout>

    <HorizontalStackLayout Margin="0, 10, 0, 10" BackgroundColor="Red" HorizontalOptions="FillAndExpand">
        <Label Margin="0, 10, 20, 10" HorizontalOptions="Start" FontSize="{StaticResource MediumFont}" FontAttributes="Bold" Text="Facility: MTY" />
        <Label Margin="0, 10, 0, 0" HorizontalOptions="End" FontSize="{StaticResource MediumFont}" FontAttributes="Bold" Text="Weight: 449 lbs." />
    </HorizontalStackLayout>

</StackLayout>

Changing from a HorizontalStackLayout to a Grid without any column definition (just a single column), seems to work. It seems the HorizontalStackLayout has issues.

<StackLayout Margin="20, 10, 20, 10" Orientation="Vertical" HorizontalOptions="FillAndExpand">
    <Grid>
        <Label Grid.Column="0" Margin="0, 10, 20, 10" FontSize="{StaticResource MediumFont}" FontAttributes="Bold" Text="Package #22J"/>
        <Label Grid.Column="0" Margin="0, 10, 0, 0" HorizontalOptions="End" FontSize="{StaticResource MediumFont}" FontAttributes="Bold" Text="Phase 1" />
    </Grid>
    <Grid>
        <Label Grid.Column="0" Margin="0, 10, 20, 10" HorizontalOptions="Start" FontSize="{StaticResource MediumFont}" FontAttributes="Bold" Text="Facility: MTY" />
        <Label Grid.Column="0" Margin="0, 10, 0, 0" HorizontalOptions="End" FontSize="{StaticResource MediumFont}" FontAttributes="Bold" Text="Weight: 449 lbs." />
    </Grid>
</StackLayout>
