Flux triggering Helm upgrade on every commit?

[comminutus]

Hi there, I have a Helm chart which I defined in the same Git repository as my Flux deployment (at /helm-charts). I reference this Helm chart in my Flux HelmChart resource using sourceRef:

apiVersion: source.toolkit.fluxcd.io/v1
kind: HelmChart
metadata:
  name: my-chart
  namespace: flux-system
spec:
  chart: ./helm-charts/my-chart
  sourceRef:
    kind: GitRepository
    name: flux-system
  interval: 1m0s

I define a HelmRelease by referencing this chart:

apiVersion: helm.toolkit.fluxcd.io/v2
kind: HelmRelease
metadata:
  name: my-release
  namespace: default
spec:
  chartRef:
    kind: HelmChart
    name: my-chart
    namespace: flux-system
  interval: 1m0s
  values:
    ...

Whenever I commit to the Git repository, the Helm controller runs an upgrade on this Helm release. How come? Upon further inspection of the deployed HelmChart, I can see that the reconcileStrategy is set to ChartVersion and the chart's version is set to *:

apiVersion: source.toolkit.fluxcd.io/v1
kind: HelmChart
metadata:
  creationTimestamp: "2024-08-02T13:03:03Z"
