Playlists won't copy to Rekord buddy

When i try to copy playlists to rekordbuddy i get a message that says

Some of the crates contains tracks that are not on the same volume as the destination collection.This is not supported by Rekord Buddy collections and any such tracks will be skipped.Afterwards no tracks are carried over.
I’m on a mac running Mojave 10. 14

There is an explanation regarding this in the manual.

You will need to create a collection on the same volume the tracks are on and then you’ll be able to drag those tracks on that volume.

If you drag toward a collection like rekordbox or Traktor, this doesn’t matter. With Rekord Buddy or Serato, it does.
