Only "see" one directory

[friki67]

Hello! I'm testing this, and it is working great for my Album directory. The thing is that it only "see" one directory in my Singleton's one.

This is my path definition

    default: Album/$albumartist/$album%aunique{} [$year]/$track - $title                                                                                              
    singleton: Non-Album/Singleton/$artist/$title                                                                                                                     
    albumtype:soundtrack: Soundtrack/$album [$year]$atypes/$track - $title                                                                                            
    comp: Non-Album/Compilation/$albumartistcomp/$album%aunique{} $atypes/$track - $artist - $title  

I did beet fetchartist /mnt/storage/data/media/music/Album and it works perfectly
But if I do beet fetchartist /mnt/storage/data/media/music/Non-Album/Singleton it only 'sees' one of my artists directory, no difference with the rest (maybe imported before some change?)
If I did beet fetchartist /mnt/storage/data/media/music/Non-Album.
Can you help, please?
NOTE: maybe it has to do with $albumartist vs $artist or my $albumartistcomp field?
