I have a Xamarin Forms Xaml based project where after showing a page the layout of some labels in the original page is incorrect.

This effect only happens as far as I can tell on Windows Phone (device or emulator). It does not happen on Android.

To reproduce the problem follow the steps below

1) Build and load the application on the Windows emulator

2) Scroll down to the bottom of the main page

3) Touch one of the ? button on the line labelled 'Time of 1st goal'

4) Touch any of the numbers shown on the next displayed page. This will dismiss the page and return to the main page.

5) The labels at the top and bottom of the screen are not rendered correctly.

Some of the labels on the MainPage seem to have been given a width which is approximately half the expected width.

The images showing the correct and incorrect appearance are contained in

I was able to reproduce this issue using the above description. 

I also noted that if I did not set the text on the Button in the TicPickMainPage from the GoalTimePage  that the TicPickMainPage did render correctly when it was displayed again. 

To verify:

1. Open the GoalTimePage.xaml.cs file
2. Comment out line 110 which is the statement:
>    actButton.Text = min;
3. Run the Windows Phone app and proceed as in the description above. 
4. Note that the TicPickMainPage renders correctly now. (However the desired text is not set for the button of course)

Thank you for taking the time to submit this report. After reviewing the description of this bug, we no longer believe it affects the current version of Xamarin.Forms. If you are still experiencing the issue after updating your packages, please reopen this report with an attached reproduction.
For your convenience, we have created some reproduction best practices viewable here: https://gist.github.com/jassmith/92405c300e54a01dcc6d
