Ok this php error is now fixed in 1.0.5 (available for download). It was caused because you did not set any profile manager for the component.
But I still can't reproduce your inital issue.
I cretated a menu item to a single game, added it to a footer menu. It still doesn't break anything in the module's menu selection list like in your shot. If you have error messages from the browser console on that page, It would be helpfull.
