Description of problem:
The customer has two storage classes:
$ cat glusterfs-storage.yaml
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  annotations:
    storageclass.kubernetes.io/is-default-class: "true"
  creationTimestamp: null
  name: glusterfs-storage
  selfLink: /apis/storage.k8s.io/v1/storageclasses/glusterfs-storage
parameters:
  resturl: http://heketi-storage.app-storage.svc:8080
  restuser: admin
  secretName: heketi-storage-admin-secret
  secretNamespace: app-storage
provisioner: kubernetes.io/glusterfs
reclaimPolicy: Delete
volumeBindingMode: Immediate

$ cat glusterfs-storage-block.yaml
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  creationTimestamp: null
  name: glusterfs-storage-block
  selfLink: /apis/storage.k8s.io/v1/storageclasses/glusterfs-storage-block
parameters:
  chapauthenabled: "true"
  hacount: "3"
  restsecretname: heketi-storage-admin-secret-block
  restsecretnamespace: app-storage
  resturl: http://heketi-storage.app-storage.svc:8080
  restuser: admin
provisioner: gluster.org/glusterblock
reclaimPolicy: Delete
volumeBindingMode: Immediate

Cluster Console: Default storageclass always shows false even if I change it to true.

Version-Release number of selected component (if applicable):
OCP v3.11.43

How reproducible:
Create a storage class for example:

$ cat mstorageclass.yaml
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: mstorageclass
  annotations:
    storageclass.kubernetes.io/is-default-class: "true"
provisioner: kubernetes.io/manual

$ oc create -f mstorageclass.yaml

Steps to Reproduce:
1. OpenShift Console -> Cluster Console -> Storage -> Storage Classes
2. mstorageclass -> Edit Annotations -> [True] => DEFAULT CLASS is false
3. $ oc describe storageclass mstorageclass // shows is default Yes but in Cluster Console is false..
oc describe storageclass mstorageclass
Name:                  mstorageclass
IsDefaultClass:        Yes
Annotations:           storageclass.kubernetes.io/is-default-class=true
Provisioner:           kubernetes.io/manual
Parameters:            <none>
AllowVolumeExpansion:  <unset>
MountOptions:          <none>
ReclaimPolicy:         Delete
VolumeBindingMode:     Immediate
Events:                <none>

Expected results:
To be true default storage class in cluster console
