Menus cause issue

When I try to change the difficulty of the game (wether in game or when editing a world) after tapping the the box to select the option and then tappingg peaceful, hard, ect. it won't let me click out of the box, so I have to exit the game completely, I tried hitting the return button on my devise, clicking anything in the game and nothing happens, so this is really annoying as I have to play all my worlds in "normal" difficulty

Also, my device is a galaxy tab A which currently isn't listed, so I selected a similar device
