Reply to S4 Master volume LEDs not working

Hey, so I'm playing a track with a decent amount of volume and the LEDs around the master volume knob are not lighting up, they never do.

Also when I adjust the master volume knob, the volume does change, but the display of the knob in traktor does not change accordingly.

This is S4 is pretty new, 1 week out of the box, but I had a store demo model for 2 months before I got the this one.

The second and third image are taken at the same time.
