Same iphone shows up as connected to gateway twice

Hi.  My son's iphone shows two connections to the xfinity gateway at the same time.

The phone recently upgraded to ios 16, and that may have something to do with it.  But it shows one connection as an unidentified device, with no other device information (i.e. no device type or manufacturer, no ios, etc), in other words, the gateway does not see it as an iphone.   The gateway also shows a second connection, this one recognized as an iphone with full device information, but still shows as ios 15.5, so this is the old device info.

We rebooted the phone and also toggled wifi to confirm that both connections were coming from the same device.

Thanks
