Thanks for your post and welcome to the forums. It's great having you on board with us in the Community.
As mentioned by our lovely VIP Tudor above, the hubs will have both bands active and combined. This is so your connection can swap seamlessly between the 2 bands if needed depending on where and how you use the device connected. We recommend leaving the bands combined to ensure the best connection however should you wish to separate them, you can do this following the thread given above by asim18 🙂
