"I have a couple of single (through hole) pad test point parts with which

location properties box not the component location properties box."

I tend to do that a lot as well. I'm getting in the habit of editing my test
points in the navigator panel.

Could this be because you were editing the pad location instead of the
component location?

I have a couple of single (through hole) pad test point parts with which
that I have noticed this - double clicking the pad brings up the pad
location properties box not the component location properties box.
