@tumido can I get more details on this issue? When I tried replicating this issue on a local argocd server hosted on openshift local, using the 2.11.4 chart, argocd doesn't seem to complain about anything?

apiVersion: argoproj.io/v1alpha1
kind: Application
metadata:
  name: janus-backstage
spec:
  destination:
    name: ''
    namespace: test
    server: 'https://api.crc.testing:6443'
  source:
    path: ''
    repoURL: 'https://janus-idp.github.io/helm-backstage'
    targetRevision: 2.11.4
    chart: backstage
    helm:
      valueFiles:
        - values.yaml
      parameters:
        - name: global.clusterRouterBase
          value: apps-crc.testing
        - name: upstream.backstage.image.tag
          value: next
  sources: []
  project: backstage-testing

The desired manifest for the volumeClaimTemplate seems to match the live manifest and I don't seem to see the issue shown in the screenshot for the issue.
