you mix up 2 rgb app's and wonder why something goes wrong, rly?
no offence - but mixing 2 apps and posting here - just wastes developers time (THEY HAVE THINGS TO FIX)....
According to a PREVIOUS POST here Aura Sync does not work with that KB. However, have you tried opening the sync software to see if you can UN-link the KB? I don't use sync or that KB so cannot try it myself. In that post Asus is telling you to use the software, in spite of the rude remark above.
