No playlists exported after a look in Finder

I have googled, read FAQ etc and there is supposed to be two folders on an usb-memmory when exported from RB with playlists etc.

I use RB 2.2.1 with Mavericks and in RB on the usb device the playlists are there, every time i reinsert it. So something has gone right, but there is only a content folder, when i update a mp3 file i see the timestamps on the folder change but not on a playlist, nothing will happen on the usb.

So when i add a playlist and resync the usb (automatic sync/sync all playlists), nothing appears except Content folder with all the music files.

What am i doing wrong?
