XDJ RX2 Stand alone help again 😥

Hi all I hope you can help me again, after following the instructions from yesterday's post, I went onto my laptop loaded up rekordbox right clicked my music folder which has many sub folders inside i.e. Deep house - Tech house - 80s etc etc when I right click a sub folder and export it to my USB its exports into loads of folders of the artists and not all in one folder as they are before I export them from rekordbox. Does anyone know a way of avoiding this ?

Also when using the RX2 with the USB the first deck loads a track but the jog wheel doesn't work i.e. It doesn't Stop when I push the platter down or spin back and also when I click play/pause it doesn't stop the music it makes it jump like a loop has been set and I can't get rid of it. But on deck to there is no problem ?
