OK. I think I figured out what's happening. My "Projects" list shows FOUR websites, all with the same name (in fact I have only ONE). The purchase of ACCORDION is attached to the WRONG "Project."

Why are there 4? When did that happen? Can't I merge them?

I'm afraid to just delete the one and "release" the add-on, for fear that it will just disappear.

Can any one help me with this?

Nevermind. I figured it out.
I had to "release" it from the wrong project, then apply it to the right one. (Then, I deleted that bunch of copies!)
