It seems you have changed the way Protected Content works in recent updates.
1. I used to have a specific menu assigned to loged in members. Now I can only select the main menu. There seems to be no way to change the menu for loged in members.
2. Is there a way to have a login/logout button in the menu, that changes if the user logs in? Every other membership site on the net has such functionality, I cannot find it in the Protected Content Plugin.
