In the midst of changing my team, my formation became 3-4-2 and refuses to let me add my 3rd striker from the bench. It also removed my backup keeper completely. So my bench consists of 1 striker, 1 midfielder, 2 defenders. Currently fielding 9 players, unable to add to my 1 open midfield position and the missing striker that appears as an empty space since he's on my bench. Help?
