Welcome to the forums @Showell1 I had this issue, its usually caused by the firmware being corrupt per what a technician told me when I asked what could be causing it. Best thing you can do is have a box swap. I am just stating what I was told by an Xfinity Authorized Contractor. You can also try a system refresh to see if that changes anyhthing. You can get the box swapped the fastest via a visit to your local Xfinity Store. Hope this helps.
