Problem/Bug Ranks In Tab (Not From Permission Plugins)

I was wondering if there was a way to get ranks in tab that are not from permission plugins. I use PowerRanks for the ranks.
Plugin List:

Ultrasmite-1.4

I hope someone can answer this problem for me.

 

I don't believe that's possible without a permissions plugin (i would suggest PermissionEx)

 

when i use permissionsex, i type in the command, and nothing happens, not even an error in chat or console
