Strange space at top of titleview in xamarin forms for UWP

Experiencing a very strange issue where the title view is cut by about 10 pixels, on UWP only, causing major UI inconsistencies with its android counterpart on a forms project.
markup is relatively simple, just a few stacklayouts, sample below, on a master detail page.
I've attached an image with a different background color, could I please ask for some suggestions? Many thanks

<NavigationPage.TitleView
>



<Image.GestureRecognizers>


</Image.GestureRecognizers>

            </Image>
            <Label Text="Edit Show" FontSize="10" TextColor="White" VerticalTextAlignment="Center" />
        </StackLayout>![](https://us.v-cdn.net/5019960/uploads/editor/bk/ufxlpzj1iclv.png "")
