Unknown new 'satellite' shown

Hi

I have the RBK853 WiFi 6 Mesh which has the 2 satellite, RBS850. Usually when I look at attached devices in the Orbi software I see the 2 RBS850 under the 'Connected Satellites' section and then a whole list of devices under the 'Connected Devices' section.

Today under the 'Connected Satellites' section there appears to be a 3rd satellite which is shown as 'XEROX CORPORATION' in the device name. Backhaul status is shown as 'Disconnected' and there is a button given to remove it.

I do not, and never have had, a third satellite. It isn't my printer which is not Xerox and is shown in the 'Connected Devices' section where it should be anyway.

Does anybody know why this could be showing as a satellite?
