Server not listing movie

Server Version#:4.51.3
Player Version#:

Trying to add the movie “10” with Bo Derek. My Plex server will not list the movie. I tried several names
10 (1979).mp4
10 Ten (1979).mp4
Ten (1979).mp4

I could believe that it may not be in the database but it should list the movie and I can add the meda data/

10 (1979).mp4

It’s matching for me. Make sure you don’t have embedded information in your file. That can throw off the matching.

Don’t know what I am doing wrong. I rerecorded it and named it 10 (1979).mp4.
It will not even list it let alone bring up the meta data. I even tried several other names to see if it will list it. No luck
This is the first move that I have had a problem like this. I also have
21 (2008).mp4
42 (2013).mp4
61 (2001).mp4
1917 (2019).mp4
1941 (1979).mp4
These all were listed with meta data no problem.

Just named it 10 test (1979).mp4 and it listed it. Then did a search on 10 Dudley Moore and I was able to find the meta data???
I hate not being able to use the correct naming convention.
