New media in the movies library matches to wrong existing movies

I cleared all the logs beforehand, and performed exactly one action with verbose logging for debug purposes. The server logs have 3k lines of logs, everything else has a few dozen. Yes there’s a bit of cruft, the logs I posted however are not “useless”. I went through them before posting. This is the server log without the verbose logging, it’s just over 1k lines still: Plex Media Server.log (183.7 KB)

I only ever have 1 movie per folder, never had more. And the specific directory structure I used has worked with Plex for years, I’ve been a Plex Pass member for 7 years, and been using Plex for much longer than that. Always with the same structure. Only had this issue this past month.

I think you mean the “preferred” name and structure. My issue isn’t that Plex is failing to match metadata or 3D type or anything like that, I manage with those issues on a case-by-case basis. My issue is that Plex is completely failing to land on an even remotely similar movie name. The main reason I use Plex is because it can handle this naming structure.

Again, I’ve have not. And I wouldn’t call “The Fifth Element” even remotely similar to “Harry Potter”.

This has happened with both adding a new version of the same movie to an existing folder (as was the case with Harry Potter, I simply removed the old file and added a new version, plex matched the new file in the same old folder as “The Fifth Element”, when the old file in that exact same folder matched as “Harry Potter”), or with brand new movies (as with Zombieland, matching “Gemini Man” (again, wouldn’t call that even remotely similar).

I object to your assessment of poor naming structure being at fault. 1700+ movies automatically matched correctly so far would demonstrate otherwise. I’ve gone to great lengths to keep the database and file structure clean, without the need to ever “Plex Dance” until now, when the issue crops up with the majority of new files added over the last few weeks.
