Things that spring to mind as possible solutions are:

is_admin()
User Role

You need to identify when the template tags you are modifying are  
called and where you do/do not want to modifed the results.

Ideally if you are in an admin page then you probably don't want to  
limit the category access unless it is for a low level user.
