Hi, I was hoping somebody could tell me what I'm missing here.  I've applied a FBM to M3, but not all of his body parts are morphing properly.  His left shoulder and left thigh and all their children parts (forearm, hand, shin, foot, etc.) don't change.  I've attached a photo so you can see what I'm talking about.

I'd appreciate your help.  I've never seen this before, and don't know what to do.
