Plex displays two movie posters of the same movie

since updating to Version 1.13.0.5023 my movies list now has random titles where it displays two of the one item

Each of the items lists the same file as item its saying it is.. the only difference I have found is when I look at the edit box.
When clicking the edit button on each.. the General information is different.. one has basically no info, the other has no info like studio etc

This problem has only shown up since the last update.. all devices list all these double ups

If i click one of the items to delete.. it deletes the file, which makes the other item useless as it then also has no file

does not explain why its now happened… but yes, thanks, it is the problem… now to edit and delete over and over and over… tedious

The collections feature was introduced with the latest version.

Not necessarily.
Just edit your movie library and set the display of ‘inline’ collections to ‘Disabled’.
It is all explained in the link.
