Movies previously matched now unmatched after update

This seems to be the same issue described here, even if for the Windows version:

Plex Keeps Unmatching Movies In My Library

Server Version#: 1.25.3.5409 Everything has been working fine until the last week. I added some new movies and went to update my library by scanning library files. It unmatched over 3000 of my movies. I manually fix all of them. Then today, 01/15/2021, I added a few more movies and re-scanned library files. This time it unmatched another 1000+ of my movies. Anyone have any ideas why Plex keeps unmatching my movies that I had already matched on my server?
