Grafana-operator chart doesn't detect dashboards

[journeytosilius]

I have configured the chart with --scan-all, but when I create a new dashboard object : https://github.com/integr8ly/grafana-operator/blob/master/deploy/examples/dashboards/DashboardWithCustomFolder.yaml, the operator doesn't discover it.

I have tried adding this to the helm chart values, since it's not in there but to no avail:
spec:
dashboardLabelSelector:
- matchExpressions:
- { key: app, operator: In, values: [ grafana ] }

I'm not sure if this is a bug or I'm missing something ?
