Yes, add plex, emby and jellyfin as separate media server entries instead of just using 1. I have been trying to for a while to get the open file/s on disk to work properly, but it keeps moving data that isn't being watched. This is likely due to the media servers doing things like extracting images, etc. If you add the 3 media servers as separate entries, then it would ignore any other file that might be open for a period of time for other reasons and only move media files.
