Store mode on hyperion duo ii question

even with the tcs set at 60% it will not discharge a pack to store mode. i need to do it with the discharge function and just set the discharge rate of each cell at 3.7. if i set it on 60% and have it as continue action it will carry on to charge to 100% anyways, so thats not a big deal im just baffled. should have stuck with the turnigy 8150 i guess
