I do not know if it matters but the release date was 10-07-2016. I do not think the day and month are use for anything but, since I do not really know anything about the inner workings of the matching engine, I think that is the only difference I see so it “might” be a problem.
Also the IMDB id is tt2119532 and the TheMovieDB id is 324786. You might try adding one or the other to your filename for matching.
I think I found root cause, I need choose “Plex Movie (legacy)” other than “personal Media” in order to get correct metadata.
However, The “Refresh all metadata” still doesn’t work, I can only search and match one by one. The issue become I have 400+ movies need to fix that issue
