Refresh Metadata not (completely) working

I renamed the genres of some of my TV shows on my Plex server. Infuse on Apple TV seems to refresh the metadata and display the genre changes just fine, but not Infuse for Mac.
On the Mac, new shows are added correctly, new artwork, etc, but the genres do not get updated. I tried going into Settings-Library and selecting “Update Metadata” manually, and also tried “Scan For Changes”, but it still does not update the genre.
Then I tried going into each TV show individually and selecting “Refresh”, and that works. Of course doing that for each show 1 at a time is cumbersome to say the least, so I’m guessing this must be a bug.
