Gateway in System Settings

Hi. Was trying to troubleshoot slow DNS at work (Kubuntu 24.04.2). I see in System Settings > Connections > Wired Ethernet > IPv4 (Method: Manual) that the Gateway is 0.0.0.0.

‘nmcli dev show eno1’ shows the IP4.GATEWAY: correctly as 192.168.1.1

Have I configured something wrong? Why is this so?
