Thanks for determining a path forward. I have used Yate tag editor, and especially so with my box sets to segregate one or more discs as described here.
However, in that solution, I unnecessarily added the album title to the Roon Album Tag in Yate. Even though I’ve used this methodology for a few years, I have not seen box sets pop up in the Roon tags until a few months ago.
Following your guidance, I removed the content from the Roon Album Tag field in Yate, but still retained the Work and Part Fields:
I then went into Roon and manually removed those box sets from the unintended tags:
and then ran a Force Rescan. The unintended did not reappear.
I think that cleaned things up. I now have only the few tags that I want to retain:
Can you run another diagnostic report to see if things are running close to normal?
