This often happens when you have multiple unimesh figures in the scene. You're going to have to load each one with morphs, save it to the figures library as a cr2, then reload from there. You should be able to copy down the dial settings from the existing pz3 so at least you don't have to create the faces again. You also should be able to save the poses from the pz3 to the Pose library so you can reapply them to your morphed figures.
