Server Version#: 1.25.0.5282
Just discovered that I have a movie named The Master from 2012 that is duplicating all the actors in it.
While viewing the movie page and clicking ANY actor, will show only one result, this movie.
Searching any actor by name who played in this movie will show two results.
Example:

Clicking one result will show only this movie, while the other result will show all the movies the actor played in.
I have removed this movie and the problem went away.
Added the movie back and the problem came back.
The file does not contain any metadata and I am not using nfo files.
Anyone having this movie on their Plex server can confirm or deny this please?
