Plex isn't separating multiple genres

Server Version#: 1.30.0.6486

My collection has been tagged with Picard/Musicbrainz and I often include multiple genres for albums, all separated with a forward slash. While Kodi is able to parse this appropriately, I’m finding that the Plex scraper is grouping everything into a single giant genre tag. Is there a way to instruct Plex to treat the slash as a delineator?

Thanks.

I’m starting to think I’m not going to get this solved. As of version 1.31.1.6782 my music genre metadata is still functionally useless.

See Only one embedded genre tag being read for details.

This was very informative, if a bit disheartening. Thanks.
