drum edits not "saving"..

Okay so I am using the drum editor in the BB Manager…I change the dB level of certain instruments in the kit, follw the defaults as BB says it has changed so I want to save, so I go ahead with all of that. BUT, if I laod the kit again, all my changes have disappeared and it’s back to the default (or factory loaded) kit.

What am I missing here? I don’t want/need to create a new kit, I just want to edit and save over the existing ones.
