Xamarin.Forms Android Entry Focus results in parent view being removed from layout

I'm using absolute layouts throughout our app to present modal pages, many of which contain entrys to retrieve input from the user. On one of these pages specifically - when the entry gains focus the entire modal panel is immediately removed from the layout for some reason. The application output is providing some clues - and I have denoted one of the lines below with an arrow where it looks like its retrieving a null input, but I cannot figure out why this is happening or how to resolve it.

Does anybody here know what I'm doing wrong?

**Application Output: (Note: The FOCUSED and UNFOCUSED text lines are debug print statements that I have inserted for testing.)
