Rekordbox USB Playlists not showing up in SC6000M?

help.

have a Rekordbox USB which i use when playing out. i’ve previously plugged it into my older Prime2 (sold a year or 2 ago) and all playlists etc were perfect (never imported in Engine… these were native Rekordbox playlists)

just updated the USB with new playlists/tunes etc in Rekordbox… and all evident in Rekordbox on my mac.

plugged it into my new SC6000M, clicked OK to update on device but NONE of the new playlists are displaying?

help!

anybody?

i swear my rekordbox native playlists were displaying on my Prime2. just tried another rekordbox thumb and no playlists
