Hi Asher.
Mike in our Tech Support has already emailed a reply to you. For information I will post it here too:

“Stereo aux sends have their own pan control independent of the channel pan control. A Follow Channel-pan function has been requested and has been slated for future development of the software, but for now, set your stereo aux pan to be the same as the channel pan position, much as you would on an analogue mixer with stereo aux sends.”

Let us know if you need any more information on this or any other aspect of using iLive.
Regards,
Carey
