Some tags not saving, Rekordbox 3.0.1

When I edit track info, such as Comments & Key, the information isn't being saved when I move to another track in the collection window. If I edit info, and move to another tab on the same track (such as Summary or Artwork) the new info is there, but when I leave the track, it's gone. This seems to coincide to when I installed Rekordbox 3.0.1, but I'm not 100% sure. It seemed be working fine in Rekordbox 3.0. I'm not reloading tags or syncing to iTunes. The issue's very re-createable. Please give me a solution other than wiping all of my data, since many of my tracks are wavs and therefore aren't stored as ID3 tags.

Thank you
