Hello,
I just noticed when I enter a battle and then select a Option like "Attack" or "Ability" and then I hit the controller button 'b' to go back in the menu, it (the menu box) appears GUI box appears lower on the screen.
However, If I select Ability and then select a ability, then I hit the Back button to go back to the first list of options the menu is fine and remains in the right location on the screen.
It is hard to explain, I hope that makes some sense.
Thank You
