Server Version#: 1.26.1.5798
Because Plex does not any 4K designators on the artwork/name, I have my 4k content in it’s own library, and each one I rename 4K - name. This keeps it separated from other files, as well as easily identifiable on your home page/recently watched. Plex is unable to tell the difference from one or the other, and you can play a 1080p version in one library, and both versions will show up on homepage as being watched, with the same watch status… so this keeps them fully separate for my users.
That said, I have been having a really annoying issue as of late where Plex has decided it will randomly RENAME my titles for me. It only does this for SOME of the movies, like maybe 10 our of 40 or so, but it consistently does this week by week. It leaves the artwork alone (I have custom covers) but changes it from 4K - name to just name. Ex: 4K - Turning Red is changed to Turning Red over and over and over. I will go rename them again and it will stick for a few days to a week, then randomly I come back and those few are changed again.
Frozen ii, The Green Mile, Turning Red, Joker are the main repeat offenders, but I have a few more that do it randomly too.
What is going on and how to do stop it?
