XDJ-RX Beat Effects malfunction

Hi, I received my XDJ-RX today and after checking out most of the features, it came to my attention that the ECHO, SPIRAL and REVERB beat effects did not work on neither of the channels. I tried all the beat effects using the control switch and the only effects that worked were DELAY, TRANS, FLANGER, PITCH and ROLL, so you can imagine how disappointed I am right now, specially after upgrading from a XDJ-AERO system. What could be happening? Hardware malfunction? Broken switch? Thanks.
