iDJ2GO cue/sync/headphone button lights not working with djay 2 on iPhone 4

Hi,

I just purchased an ION iDJ2GO and when using it with djay 2 on my iPhone 4 (ios 6.1.3) the cue, sync, and headphone buttons do not light up. The buttons do function properly, its just that they don’t light up. However, the play/pause button does light up.

I’m wondering if it is a midi mapping issue with djay 2, or an actual hardware problem with the iDJ2GO. Thanks.
