Unable to unselect "Hard" on difficulty level in Naval Academy.

[Ernst Preuss]

In the Naval Academy screen I inadvertently clicked in the difficulty icon and it changed to "Hard". Now I can't change it back to 'Standard" or "Easy".  What is the key to change it?

Thanks for an excellent game.

Greetings Admiral! Difficulty level is a placeholder right now and is not working yet.
