How Deep can sub-forums go?
 

I would like to organize forums by State and then have local chapters in each state.
When I set up the local chapter it shows up on the state level* even though I flagged it as being a child of a local state.

In other words on the Main Category page we see "Forums By State" (as expected) which leads to "Alabama Chapters"* which leaders to the local chapter. The problem is that the local chapter listing is also showing up on the state page.

Is there a limit to how deep sub-forums can go?
