enablePVReclaim doesn't work

[HarrisChu]

1. create a nebulacluster resource by using

apiVersion: apps.nebula-graph.io/v1alpha1
kind: NebulaCluster
metadata:
  name: {nebulacluster_name}
spec:
  graphd:
    config:
      heartbeat_interval_secs: "1"
    resources:
      requests:
        cpu: "500m"
        memory: "500Mi"
      limits:
        cpu: "1"
        memory: "2Gi"
    replicas: {graphd_num}
    image: vesoft/nebula-graphd
    version: v2-nightly
    service:
      type: NodePort
      externalTrafficPolicy: Local
    storageClaim:
      resources:
        requests:
          storage: 2Gi
      storageClassName: nfs-client
  metad:
    config:
      heartbeat_interval_secs: "1"
    resources:
      requests:
        cpu: "500m"
        memory: "500Mi"
      limits:
        cpu: "1"
        memory: "1Gi"
    replicas: {metad_num}
    image: vesoft/nebula-metad
    version: v2-nightly
    storageClaim:
      resources:
        requests:
          storage: 2Gi
      storageClassName: nfs-client
  storaged:
    config:
      heartbeat_interval_secs: "1"
    resources:
      requests:
        cpu: "500m"
        memory: "500Mi"
      limits:
        cpu: "1"
        memory: "1Gi"
    replicas: {storaged_num}
    image: vesoft/nebula-storaged
    version: v2-nightly
    storageClaim:
      resources:
        requests:
          storage: 1Gi
      storageClassName: nfs-client
  reference:
    name: statefulsets.apps
    version: v1
  schedulerName: default-scheduler
  imagePullPolicy: IfNotPresent
  enablePVReclaim: true

2. delete the nebulacluster

expected result:
delete pvc

actual result:
doesn't delete.
