DDJ 1000 back spin lag

Whenever I back spin on the DDJ 1000, sometimes it stops and doesn't back spin smoothly.  I'm noticing a little of a lag too while you spin the jog wheel platter.  I'm not using any other software but rekordbox.  Is there a setting i need to maybe tweak for a smoother backspin.  the jog adjustment is set to light, not heavy. thanks.
