3rd underforum not shows in the 2nd underforum

[tomtom1984]

Hi,

i try all the time to not show the 3rd hierarchy of the forum.
At the moment shows like:

Forum XY

1-Vital

2--BBB

3---BBB
3---|BBB WIRK <- not shows in the 2nd only in the 3rd his own hierarchy
3---|BBB NEBN <- not shows in the 2nd only in the 3rd his own hierarchy

1-Ernäh
1-Sport
1-diverses

What have i done:
I created a new templates like:
forumhome_forumbit_level3_nopost & ....level4...
forumhome_forumbit_level3_post & ....level4...

In the backend:
Foren->Display Sequence:

[LifesGreatestGift]
