Duplicate Artist Entries

Running Kodi 16 on my QNAP TS-251.

I just cleaned up my music library by running it through musicbrainz picard. Now I’m seeing duplicate artist entries when browsing by artist but only for some albums. I checked the artist vs. album artist fields and they’re identical. I’ve updated the tags and still seeing the problem. I’ve removed my entire library and re-added. I’ve added just the one artist I see this issue with consistently. I’m at a loss on what the issue could be.

Any suggestions on what to check next?
