Please Help, Problem When Creating Subforum Under Subforum

[Doksh]

Hello,

i'm facing a strange problem that when i try creating a subforum under a subforum

Like :

[ Main Forum ]
->[ SubForum ]
-> anotherSubforum

it goes like this

[ Main Forum ]

-> anotherSubforum
->[ SubForum ]
-> anotherSubforum

the subforum i created in the subforum it appears also in the mainforum !!

i don't know how to make only the subforum only appears under the subforum not in the main forum ..

Here some photos discuss more the problem :

here the main forum is : OS Zone and subforums are Linux - Windows - Mac



i'm trying to add another subforum under subforum Linux named " Tools "

When i adding it appears under the main forum " OS Zone " and also under " Linux "



i don't know how to make it only appears under linux subforums ..

Please Provide me With the Solution for This Problem :erm:
