Missing "IP Address" in Supervisor > System page

I can’t configure IP address using the web interface anymore.
The “IP Address” line missing in Host section (see screenshot)

How can show it again?

I am running Home Assistant supervised on Pi 4

On side note, my AdGuard Home add-on suddenly broke.
Upon checking it’s missing listening to the local IP anymore.

I think this issue is related becase AdGuard couldn’t detect if I use static IP or not.
