I had an issue with the latest update which cause the system to be unstable. I deleted my deco wifi network and attempted re-added a new network with same name and password. Unfortunately when I tried to add the network back through the app, I get a message that I need to use a different name for the new network due the another deco device has the same name. I checked both my pixel phone and PC and sure enough it still listed in the available wifi network. i see all  three of my old network(2.4/5, 6  and lot). They are not showing up in my saved phone, PC network anymore so I can't delete them. It also not showing up in the deco app.  How can I remove these ghost deco networks?
