The problem is that I don't see the link forum there
You could do the following: Copy the contents of template forumhome_forumbit_level1_post to the template forumdisplay_linkbit_level1 and the template forumhome_forumbit_level2_post to forumdisplay_linkbit_level2
If everything works, alter the two linkbit templates to remove the contents you don't need, and everything should work fine...
