tested with 4.8.0-0.nightly-2021-05-21-233425, there are 3 dashboards on "Monitoring -> Dashboards" have dropdown filters that should default to "All", but Kubernetes / Networking / Pod -> Namespace field should default to "All", but it sets the default to the first value in the list, usually openshift-apiserver Kubernetes / Networking / Namespace (Pods) -> Namespace field should default to "All", but it sets the default to the first value in the list, usually openshift-apiserver Prometheus / Overview -> Job,Instance fields default to "All", no issue for this dashboard

This looks like the expected behavior. We only use "All" as the default value when the dashboard definition explicitly states that we should. Grafana seems to have a different behavior of also defaulting to "All" when no default is specified. Specifically, we are looking for the following in the JSON dashboard definition: "current": { "selected": true, "value"" "$__all", }
based on Comment 7, only the "Prometheus / Overview" dashboard, which use the grafana-dashboard-prometheus configmap has the JSON dashboard definition: "current": { "selected": true, "value"" "$__all", } and Job,Instance fields default to "All", set to VERIFIED
