How are multiple downloads of the same episode handled?

I downloaded several versions of the same episode of a show because I wanted to be able to try different versions if my Plex server choked on one.

But only one episode made it over to my Plex tv folder. Why didn’t they all make it over?

Sonarr does not support multiple files for one episode.

Odd, I thought I read something about “merging and splitting”. Maybe that’s radarr?

nope none of the *arrs (Radarr/Readarr/Lidarr/Sonarr) support multiple files/versions per movie/book/song/episodes
