Where did the old metadata come from after re-install plex?

Hi,

I installed plex on my nas yesterday, some of movie files’ names were not standard. i.e., “01 The Terminator - Action 1984 Eng Subs 720p [H264-mp4].mp4”.
After installing, the “Title/Sort Title” of the movie is “01 The Terminator - Action 1984 Eng Subs 720p [H264-mp4]”, and plex could not find the poster for it.

To match it, I changed the title into “The Terminator” and the “Orinally availiable” to 1984. I canmannually match and find the correct one, but I cannot update it. the “Title/Sort Title” were not locked.

Today, I uninstalled plex, renamed the filename into “The Terminator.mp4”. Then installed plex again on my QNAP nas again. After installation, the “Title/Sort Title” of the movie is still “01 The Terminator - Action 1984 Eng Subs 720p [H264-mp4]”, and it still cannot be matched by plex.

I tried scan libirary files, refresh all metadata, nothing helps. How could I make a clean installation without the old wrong metadat?

Thanks a lot!

Are you using the Legacy Plex Movie agent? If so you should change the order of the agents in Settings -> Agents -> Plex Movie (Legacy) and move “Local Media Assets” below “Plex Movie (Legacy)”.

If you’re using the new Plex agent just make sure you haven’t enabled the “Prefer local metadata” in the Advanced section when editing the library.

Hi, I chose"Plex Movie" in both “Scanner” and “Agent”. And also, I tried to set “Agent” to “The movie databse” too. And after that, I Refreshed All Metadata But I got the same result.

Is there any option that can totally reset/erase all metadata? Or could please tell me , should I mannuly delete some database legacy by ssh?

Thanks a lot.

find -name .@__thumb -print -exec rm -rf {} \;

There are tags inside mp4 files, use mp3tag to remove them.
