Ingress-rules not displayed (just the default host)

[stefan2904]

I have the following Ingress configuration (which is working):

---
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: nginx-ingress1
  annotations:  
    kubernetes.io/ingress.class: nginx
    certmanager.k8s.io/cluster-issuer: letsencrypt-prod
spec:
  tls:
  - hosts:
    - nginx-ingress1.example.com
    - nginx-ingress2.example.com
    secretName: letsencrypt-prod
  backend:
    serviceName: nginx-example1
    servicePort: 80
  rules:
  - host: nginx-ingress1.example.com
    http:
      paths: 
      - path: /
        backend:
          serviceName: nginx-example1
          servicePort: 80
  - host: nginx-ingress2.example.com
    http:
      paths: 
      - path: /
        backend:
          serviceName: nginx-example2
          servicePort: 80

So there are two hosts (mapped to two services) plus a default host (mapped to one of the services).

Unfortunately spekt8 only renders the default host:

My expectation is that this Ingress is supposed to point at both services.

(I am new to kubernetes, so I am not sure if I used the correct terms for the mentioned concepts, e.g. "Ingress rule" and "default host".)
