Games not showing in 'Play' tab Thread

As shown here, I have added several (already installed) games via Setting > Games menu. However, when I go to the Play tab, only half of the games appear (which appeared during the install wizard). I've restarted Desura and my computer, I've tried things that come up in similar threads, but to no avail. Unless I've missed a very obvious post in my searches (which I may well have), I apologise if so.

New user, sorry if this is the wrong section or whatever.

Thanks, in advance.
