Why did some of my Artist metadata in Music change?

I don’t have much classical music in my library, but the little I do have had my eye twitching in regards to how to tag it haha so I can only imagine what it must be like to have composers lumped in with conductors or whatever else is happening with yours.

So far I’m okay, it’s various artist albums that are the problem for me. so far my “fix” is working, but I haven’t ran a plex dance to confirm nor trust that another update will knock it apart.
