Plex is MP4/M4V Challenged. Have been since Plex was born.
The LMA Hack is quicker than REMOVING the embedded Title Field in all your MP4/M4V files. That name you see is the Embedded Title Field and Plex PREFERS that Title, even over a perfectly named file.
Note:
If your files were MKV - you wouldn’t have this problem.
Plex can ONLY read internal metadata for MP4/M4V files.
