rbr50 & rbs50 satellites show on then off in AP mode

The Orbi is connected in AP mode to a Cujo fireware sitting between the Orbi and the Xfinity (Comcast) cable modem/router.  Wifi is turned off on the xfinity.  The Orbi basic screen shows scrolling text for satellites under attached devices.  This text shows 2 satellites (which there are), then 0, then 2 again. This scroll repeats. Under attached devices, the 2 satellites show.  Would like to know if there is a problem here or not.  Cujo worked fine under router mode but could only see the main orbi device.  Any traffic flagged as potentially dangerous was reported as coming from the Orbi.  In AP mode, Cujo sees all attached wired or wireless devices individually.  That's nice, but I wonder about the strange scrolling behavior on the basic screen.  Insight appreciated.
