Cannot create two couchbase clusters with one deployment of operator

I have a Couchbase cluster running on Azure AKS

Operator version: 1.0

K8s version: v1.11.2

I have a couchbase cluster with name: cb-op-aks-demo

$ kubectl get pods
NAME READY STATUS RESTARTS AGE
cb-op-aks-demo-0000 1/1 Running 0 6d
cb-op-aks-demo-0002 1/1 Running 0 6d
cb-op-aks-demo-0003 1/1 Running 0 6d
cb-op-aks-demo-0004 1/1 Running 0 6d
cb-op-aks-demo-0005 1/1 Running 0 6d
cb-op-aks-demo-0006 1/1 Running 0 6d
couchbase-operator-6cb7687498-zfzq5 1/1 Running 3 6d

Its all working fine.

Trying to create one more couchbase cluster fails
