I have two Bitdefender Premium Security subscriptions expiring in March. Each subscription has 10 seats but only 5 devices installed. I renewed one subscription, then tried to move devices from the second subscription to the extended subscription. When I tried to change the devices, it showed the renewed subscription has 7 devices, when there are only 5 listed on the subscription. This is keeping me from using all 10 seats on the extended subscription. What's taking the other two seats?
