Question GroupManager Inherit

I have a server that is very new, i got groupmanager and made all of the groups. I used inheriting so that each rank had the inherits done. Sadly i typed in the wrong thing and now default has moderator and builder permissions aswell. I tried /mangdeli default moderator and the other way around but it would just say 'Default does not inherit of moderator/builder directly'. I do not understand how to get rid of default inheriting from them, any help is great, please help me!

Thank You!
