I had the same problem. Thanks to this thread I was able to figure it out without asking a dumbass redundant question.
But the reason it was a problem in the first place was because, after setting the global forum Register-To-View flag, I then went and created a category that was set to All-users. Would it be a good idea to either disable the All-users choice from that category- Or even better, show an error message when the admin tries to set a forum to All-users if the Register-To-View flag is set.
