CKA Exam 4 Q15 issue

I am not sure how is ti possible?

I also tried to modify the GatewayCLass object:

apiVersion: gateway.networking.k8s.io/v1
kind: GatewayClass
metadata:
labels:
app.kubernetes.io/instance: nginx-gateway
app.kubernetes.io/name: web-gateway # this has replaced the nginx-gateway as we have created new gateway
app.kubernetes.io/version: 1.6.1
name: nginx

spec:
controllerName: gateway.nginx.org/nginx-gateway-controller

but still no luck in making connections. Any ideas what is wrong with it?
