Since you are not following the naming standard, it’s most likely matched as something else
I not only recommend a separate directory for each movie, but also that you follow the standard
Ref: https://support.plex.tv/articles/naming-and-organizing-your-movie-media-files/
As such, naming should be:
Dead Reckoning (1947) {tmdb-20663}/Dead Reckoning (1947) {tmdb-20663}.m4v
Also, you have your medias in the QNAP share named Multimedia
That is also not recommended
Ref: Qnap faq.....read me first!
