copy forumhome_forumbit_level2_post and create a new template forumhome_forumbit_level3_post using the same contents.

copy forumhome_forumbit_level2_nopost and create a new template forumhome_forumbit_level3_nopost using the same contents.

go to vBOptions > Forum Home Options > Set Depth of Forums

Change this to 3 instead of 2.

If it didn't work, try changing a different one, but once you have got the right one then it will display as your middle picture.
