"Ghost network" appeared with the same SSID
Hello. I had been using my mesh network consisting of 3 Deco S7 units without any issues for a long time. After running some tests, I realized that two units provided sufficient coverage and speed, so I decided to remove one of the units. Using the Deco app, I first changed the main Deco, then removed this "old" main Deco from the network. When I did this, the removed unit reset itself and its light turned blue. Everything was normal up to this point. However, after connecting the new main unit to the ONT device and regaining internet access, I noticed that a new network with the same SSID had appeared in the Deco app.
Currently, my network is working perfectly with two units (the main unit is connected to the ONT device and operating in PPPoE/router mode, and the second unit is connected via Ethernet to the main unit). However, in the Deco app, another network with the same name appears. This "ghost" network shows the unit I removed earlier, along with the two units I'm currently using. Naturally, this network is offline and I can't access it.
My concern is that if I delete this old network, my currently functioning network might also be deleted, since the two devices listed under the old network are also part of the active network with the same name.
Why could this have happened, and if I delete the old network, will my new network that includes the same Deco units also be deleted?
Both of my Deco S7 units are running the latest firmware (1.5.2 Build 20240927 Rel. 68997).
