Rekordbox 6 - Export to USB Stick for XDJ-R1 not possible

in Rekordbox 5 i had to go to settings to choose the XDJ-R1 as target for exporting librarys and playlists, however in Rekordbox 6 this option is not there anymore. how do i set this up? the R1 always complains that i shold export the library using rekordbox if i just use a folder, and it does not find the library/playlists that i actually did export with Rekordbox 6 while the folder structure looks right, it seems like the db does not fit
