I was able to restore the collection using the directions found here:

That said, it was really more of a workaround than an actual solution. I would feel better about it if I didn't have to go outside of Rekordbox to accomplish it. Please let me know if there's something I can do to ensure I'm able to leverage the edb backups in the future.
