Can't get single with a .feat artist to be placed in albumartist/album/track, ends up as artists/track

[EmberLightVFX]

Hi! I'm trying to learn beets and so far it's working great!
I have one problem with the single One (feat. Saro) by Slaters
When I let beets index it it wants to set the song as Slaters & Saro - One
Checking the musicbrainz I can see Slaters as the artist of the single (https://musicbrainz.org/artist/9fcdc20f-e835-412a-86ad-84be1a7b44a9)

In my config I'm using these paths:

paths:
  default: $albumartist/($year) $album%aunique{}/%if{$isMultidisc,$disc - }$track - $mySongartist$title
  singleton: $albumartist{}/($year) $album%sunique{}/$track - $mySongartist$title

I'm really confused on what's going on and how I can solve this.
Any help would be more than welcome.
Thanks!

maybe the "feat in title" plugin will help you
