Conflicting Genre Tag - mp3tag vs. Lumin App

Hi, When updating the genre tag in Mp3tag I’m finding that the Lumin App does not reflect the updated tag and places the file in the “[unknown]” section of the Genre display when I set it to “Jazz” for example. The change of Genre works OK for most files, but some do not and I experience this issue. I’m not sure why so thought this may be the best place to start. Upon reloading in mp3tag the Genre remains as “Jazz” so that seems to work? I’m using v1.9.8 of Mp3tag, MinimServer 2.2, Lumin App 1…

I think at this point it will need some direct input from @Florian since I think all other potential solutions and workarounds seem be exhausted.
