Found the problem

The root cause is ControlRig doesn’t control Manny mesh extra bones.
Changing preview to _Simple fixes the problem

BTW, I found the extra bones in Many mesh are super useful for some animation problems, i.e. the candy wrapper.
I didn’t understand the solution, can you describe more informatively?
