STEPS TO REPRODUCE

helm template ./charts/dgraph --values -  <<EOF
fullNameOverride: jmdg
global:
  ingress:
    enabled: true
    alpha_hostname: alpha.example.com
    ingressClassName: alb
    annotations:
      alb.ingress.kubernetes.io/scheme: internet-facing
      alb.ingress.kubernetes.io/target-type: ip
  ingress_grpc:
    enabled: true
    alpha_grpc_hostname: grpc.example.com
    ingressClassName: alb
    annotations:
      alb.ingress.kubernetes.io/scheme: internet-facing
      alb.ingress.kubernetes.io/target-type: ip

EXPTECTED RESULTS

The grpc should only have a single host key, e.g.
