metadata_backup is not backing up multiple Editions of movies

Describe the Bug

The following will output only one Edition of a multi-Edition movie.

    operations:
      metadata_backup:
        path: config/Movie_Backup.yml
        sync_tags: true

For example "That Thing You Do!" has two Editions (of I have both in Plex): "Theatrical Cut" and "Extended Cut." In the outputted "Movie_Backup.yml" file I only see this ONE result for the movie, which is the "Extended Cut":

  That Thing You Do! (1996):
    title: That Thing You Do!
    year: 1996
    summary: THIS EXTENDED CUT IS FOR MORE MATURE AUDIENCES 18+ (THE THEATRICAL CUT IS 14+) - A local Pennsylvania band scores a one-hit wonder in 1964 and rides the star-making machinery as long as they can, with lots of help from their manager.
