Why isn't the bone staying aligned?

Yesterday the bones were working fine, and a finished a small animation using the same body parts as I am now. I accidently deleted that rigged character so I am redoing it today. Initially, I applied no mask since these are already transparent and I wanted to see if I could save time. The bones didn’t work. I applied a mask around the outline. The bones still don’t work. Why don’t the points remain aligned with the part after I link them? It results in wonky rotation as seen in the attached pictures. My version is 1.4.4.
