Sub Sub Forums

[basil2070]

So I have this forum called "Staff Room" under the category "Hidden Groups." Inside the Staff Room forum, I have another forum called "Staff Folders." What I want to do is add a forum inside the "Staff Folders", but when I do this they look different then normal subforum listings. For example, all of the forums are not actually inside the forum, but they are listed below it. See the first attachment. Then, when I click on the Personal Folders Forum, I get those same forums listed below it, inside of it as well.

Anybody can help me so they aren't showing up twice.
