Adding props to "head" folder moves other layers in rig

~70% of the time I add something to my "head" folder in a puppet, it will shift everything in the head layer in a random direction back in the rig. I am using photoshop for my puppets and have my puppets rigged up like +Character - Head folder - Body folder 

Not sure I have ever seen anything shift when adding things to my body folder which contains the body/legs/arms of the puppet. 

Mainly I have to quickly rig puppets to move things in front of their faces at times. 

Appreciate any help! =]
