Rekordbuddy dublicate existing tracks

I use Traktor 3.2.1, Rekordbuddy 676 and Rekordbox 5.8

When I drag new playlist with existing in rekordbuddy, the program dublicate them.
I think this is a bug?

Same here, I have tripled the size of rekordbox collection with this

A few questions for me to better understand this.

  • Are you dragging a playlist into a folder when this playlist already exist?
  • Are the duplicated tracks in the playlists or in the collection itself?
  • Can you check what the file location listed for two duplicated tracks? Are they the same?
