Rekordbox Related Tracks gear customize criteria not working

Hi

When I go into rekordbox in the related tracks, If I click the customize criteria gear it doesn't show anything. Before, it popped a menu with options to show the related tracks by bpm, genre, playlist etc...

I also notice I now have a related tracks folder. If I do it through a folder it works but I don't want it this way since I don't have the control to filter it out through a playlist.

Thanks for your help,

Martin
