Istio ingressgateway not syncing LDS with pilot ( for 443 configuration )

1

I am using istio 1.1.10 in a 1.13 gke cluster.
Our istio deploy is done via helm.

We are deploying an istio-ingressgateway and we want to listen to 443 requests with cert manager support.

When I execute this command

$ istioctl proxy-status istio-ingressgateway-xxxxx

I see this output

-               }
-            },
-            "filterChains": [

..

This means, the envoy configuration is not merge with the pilot one.

Why this could happen?

Also proxy-status output this
