BPerms acting weird! Help!

I use BPerms and everything is set up correctly under my understanding. The only weird, frustrating glitch is when I type a prefix or suffix for any group, it appears twice.

For Example : When I set the prefix for Default group I put prefix: 'Default'
and then when default members talk it shows DefaultDefault (Playername)
Any suggestions or advice I can get? Thank you so much.


P.S. Yes everything is written correctly in BPerms.. I checked it
