GT-AXE11000 with 2 RT-AX92U 3.0.0.4.388.22525 Open SSID

[AnarchyPR]

I have GT-AXE11000 as main with 2 RT-AX92U as nodes all using version 3.0.0.4.388.22525. Last week i saw an unknown device connected to my wifi. Looking into it i found the the router would duplicate my ASUS_5G (WPA2/3) with a ASUS_5G (Open). I don't have any guest enable and my Nodes are connected wired.
Since i could not find a solution a reset my network and it was fixed.

Yesterday i found yet another Open SSID named ASUS_5G_DWB (Open) I have the nodes set as Ethernet Backhaul Mode. I disabled this mode and re-enabled and it was fixed but i have no idea with this is happening, or if someone has seen the same issue.

Dealing with this myself. There's an open SSID identical to my main name that has no security along with my main SSID with a "_dwb" afterwards. Any true fixes? I tried disabling the wired backhaul and re-enabling. Didnt fix it.
Using the same routers as OP too
