I just tried to swap out my tank to a different tank and it asks whether it is a new coil or old coil. I select new and hit the fire button, but it will not accept the selection. I swapped out to a different tank with same results. Both of these tanks work fine on my Smoant BS mod. I have removed the batteries from the Procolor and waited a bit. Still same issue. Any thoughts as to what I am doing wrong?
