The pbm's are "Partial" as in "part of a larger set of inter-related morphs". For instance, if you look in the dials for the figure's chest and see pbmMuscular1, then this is a morph which would be adjusted through use of the Full Body Morph (fbm) called Muscular1. To make it work, what you want to do is look in the "Body" section of the figure, and find fbmMuscular1 (or it may just be called Muscular1) and adjust that dial instead of the pbm dial. For full head morphs, you can also see pbm's in the individual face parts (like the nose or upper lip) while the full morph is in the "head" section. - Drew
