Rekordbox doesn't export active loops

Hello,

I have a last Version of Rekordbox 6.0.4 and I want export my active loops, but it not happens.

I can see in performance mode the red symbol of active loop

wenn I go in export mode, it disappear AND I have the hidden option ON

Also if I play the track with active loop in export mode, it doesn't loops automatically.

If I sync the playlist with my USB and then show the track from USB in performnce mode, it is there

Then I play the track on the XDJ-1000 mk2 - hot cue A is displayed as a LOOP but is not active - as the player comes to this point no loop will be activated.Do I must turn something on on the player? Or it is on this player not supported? 

Than you
