I usually knock them out on the shapes tab. I have something that keeps setting Teen Julie to 100% on Genesis 3 female, haven't gotten around to finding out what's doing it, but you'll find the character there. Until you do locate the culprit, you'll need to lock that morph to 0% after you fix the figure or some poses will put that morph right back in. It's likely cause by a new character you purchased where the morphs are in the wrong directory. There are others here who can get more specific on that for you than I can.
