just to be sure. You are clicking the empty body parts and not the filled ones?

Ohhh no I am not! I thought I was clicking on like, the arm, because the sprite doesn't have an arm so it made sense to me that I'm selecting an arm to build them an arm? I'll try again. Think the UI could do with being a bit clearer for that as I think someone else had similar issues figuring it out!
