Bug? Hidding from "users" section in toolbar not possible?

When I go to EasyDiscuss -> Settings -> Layout -> Toolbar -> Show Users = No then the discussion board toolbar still shows the "users" tab. When I disable the badged or other elements in the same section its working. However only users couldn´t be hidden. Could that be a bug or do I need some special configuration?

P.S.
If that is a bug i need a hotfix :-)
