DDJ 400 Outer Ring Jog Wheel Issue Adjusting BPM

Not sure if it's a hardware issue or software setting, but the outer ring of either jog wheel will not adjust the BPM of the track in Rekordbox anymore. 

Tried with vinyl mode on/off, same outcome. With master tempo turned off it will do a temporary pitch bend while you jog it, with MT on, nothing happens. 

Re-installed Rekordbox, as well as tried on multiple computers, Windows and Mac. 

No firmware updates that I am aware of for the DDJ-400. 

Any suggestions?
