Only Content folder - no playlists

Hi,

I have the Corsair Survivor Stealth (Flash Drive, 32gb) and RB 3.3.
I exported/syncronised all my Playlists onto my USB drive and I can see in RB that they are on the usb.
But when I put it in my CDJ-2000Nxs (lastest firmware), it only shows me the content folder.
What is the problem here?
