Thanks...

Still a bit strange that it displays that entry... especially with a
generation that seems newer than what I thought was the actually last
generation on the fs.

Snapshot destroy is a 2-phase process. The first phase deletes just the
root references. After it you see what you've described. Then, later,
when the cleaner thread runs again the snapshot's root item is going to
be deleted for good and you no longer will see it.
