deployments getting restarted without any change in git

Checklist:

[x] I've searched in the docs and FAQ for my answer: https://bit.ly/argocd-faq.
[x] I've included steps to reproduce the bug.
[x] I've pasted the output of argocd version.

Describe the bug A git change in one of micorservices triggers restart of all the microservices in the cluster. An argocd app corresponds to each microservice. I am using application-set-controller for these microservices which inturn is installed through app-of-apps pattern. The common part of microservices is a set of common templates and common values.yaml file. Each microservice has its own values.yaml files also in a microservice specific folder.

To Reproduce App-set-controller definition

apiVersion: argoproj.io/v1alpha1
kind: ApplicationSet
metadata:
  name: backend-applications-microservices
  namespace: argocd
spec:
  generators:
  - list:
      elements:
      - cluster: dev
        url: <url>
        values:
          service_name: "app-1"
          service_namespace: "backend-namespace-01"
      - cluster: dev

      - cluster: dev
        url: <url>
        values:
          service_name: "app-3"
          service_namespace: "backend-namespace-01"
  template:
    metadata:
      name: '{{cluster}}-backend-{{values.service_name}}'
    spec:
      project: my-project-01
      source:
        repoURL: <git_deploy_repo>
        targetRevision: master
        path: helm/{{values.service_name}}
        helm:
          releaseName: '{{values.service_name}}'
          valueFiles: 
            - ../base/values.yaml
            - values.{{cluster}}.yaml
            - .values.{{cluster}}.yaml
      destination:
        server: '{{url}}'
        namespace: '{{values.service_namespace}}'
      syncPolicy:
        automated:
          selfHeal: true
          prune: true
        syncOptions:
        - CreateNamespace=true
  syncPolicy:
    preserveResourcesOnDeletion: true

Structure of mentioned above looks like this.

Expected behavior

If i make a change in one of the apps lets say i change any value in app1/values.yaml, argocd should start only app-1 to make it effective but not app-2.
