Plex Media Server Windows - Displays duplicate items in error

[pshanew]

I’ve seen it suggested in another thread that duplicates with the exact same file path can happen if two processes initiate a library scan at the same time and find the same new items. There may be other ways to correct this, but you may be able accomplish it by performing the Plex Dance on the affected episodes or series. You could test this with one or two to ensure it works and then do the rest in bulk.
