Edge 130 course I delete keeps appearing after a sync

I keep deleting a course I had initially created that I no longer want, but it keeps appearing after I sync.  I delete again, and boom -- there the next time I sync.

I've even looked at the files when charging, and I don't see the course there.

Any ideas?

It has no summary, map, elevation -- nothing.  But it was from a course I created from an old trailforks ridelog that I was using to test course creation.
