Iv never had an issue in 6 years of media moving on its own lol I have a share on UnRaid called R720XD in there i have a folder called Plex in the Plex folder i have individual folders for
24bit Hig Res
4K & UHD
In the Emby docker where it says media i put the folder Plex and that then puts all the folders in Emby i just add them, Add Tv Shows and path would be
/movies/Tv Shows (Sourced)
/movies/ Tv Shows (Encoded)
/movies/ Music Videos
and so on iv never changed the layout of the folders
Are you sure that you haven't mounted the TV Shows folder into the Kids show path?
If all your Unraid shares have the same root path suggest that you try to mount all shares from a common point.
E.g. instead of mounting /mnt/user/movies --> /mnt/movies & /mnt/user/tv --> /mnt/tv
Mount everything with /mnt/user/ --> /mnt/unraid, then you have all your mounts available with one path and can easily add the libraries from Emby.
