Not enough information. What Body? What Head. Character Animator? Puppet Pin?
We need workflow details and a screenshot that shows the entire AE interface and the layers you are having problems with. Make sure you reveal all modified properties of the layers by pressing the U key twice. Then just Print Screen if you are on a Windows Machine and paste to the reply field on this forum or use Shift + Ctrl/Cmnd + 3 on a mac and drag your screenshot from the desktop into the reply field. Then maybe we can help.
