Cannot see the menu buttons. They are schrink to the left

Hi,

 

version in English. We play on an ipad with the version 1.16.50 (cannot update to more recent version). While trying to reduce ipad screen luminosity, it seems like the maneuver has affected the menu buttons ("Resume", "Parameter", "Save" - see attached image).

 

I desinstalled and reinstalled the application. That has not solved the issue.  I looked into some forums. I found nothing.

 

I need your help.
