I have a Vigor2765ac with a single operational SSID on 2.4GHz and another single SSID on 5GHz. The router is running the latest firmware V4.5.2_BT. There is also a wired access point AP903ac

I recently used a WiFi analyser on my phone and found 2 extra hidden SSIDs, one on each of 2.4GHz and 5GHz radio channels.

The MAC addresses are similar to those from my Router, but my other SSIDs on both 2.4GHz and 5GHz are actually set to "disable", so are off

Additionally these two hidden SSIDs appear to be set to WPA2 / WPA3 and my router settings are WPA2 and NOT WPA3.

Can anyone advise what they are doing and how to switch them off please
