(root node) numbers won't change organization

I have a forum listed with over 50 Categories / Forums. I have 11 Categories, and over 50 forums.

My question is, I have those 11 Categories listed under (root node). When i try to change the order of the last topic on the forums to "(root node): #1", it keeps it in last place, and won't change it. Any ideas?
Nevermind, I think i figured it out. I'm dumb and had some numbers repeating in Display Order. (Example, first three forums had #1 in Display Order).
