Small number on movie posters?

There is a small number in upper left corner of a few movie posters. Does anyone know what the number signifies? Thanks.

It means that Plex has placed more that one video file under that label. Plex often does that when the naming is not perfect and it automagically matches two different files to the same metadata.

If the blending is incorrect you can use the “split apart” function to split them and then use “fix incorrect match” to get a correct match.

But first I would use something like “FileBot” to get the file name correct.

Thanks. This explains the number and splitting apart solved the mystery.
