Scroll wheel to weapon on back / Number 3 not working

[Slimdickens]

As the title says.  For admins it works but for normal players they get the option to change to weapon on back but nothing happens.  Same if you hit 3.  I know the code is there so something is blocking it.  Im guessing Infistar or BattlEye but no matter what phrase i use to search i cannot find a single thing on this.  All other scroll wheel options work like take clothes, check body, etc...  I have scroll wheel checking set to false in AH so i am at a total loss.  Any help would be appreciated.  Thank you.
