After purchaseing BE800 WiFi 7 router and the RE605x to create the one mesh, I returned the 605 for the RE815XE.  I factory reset the 605 and unbinded it from my account.  However I see the 815 nd my main router, but under the main router it still shows the 605 (satiliate) under the router.  How to i delete this device.  Any help would be greatly appricated.  

Also in the App under Mesh Network is where I see the 605 but the 815 is in its own tile not under mesh network and all say cloud devices.
