music – Incorrect Album Artist and First Track in Plex

I ripped my parent’s Christmas CD collection as FLAC files with Windows Media Player. The first track of every album is just titled “Track 1” and the album artist of every album is “Various Artists”. They look fine in Windows Media Player, what went wrong?

If I go in and select “Fix Match” it will initially set the album artist’s name correctly before renaming them to “Unknown Artist”. The description and artist photo remain.
