[Bug]: Error "multiple matches for labels: many-to-one matching must be explicit (group_left/group_right)" on Kubernetes/Networking/Namespace (Workload)

[gsmith-sas]

What happened?

The CURRENT STATUS table of the Kubernetes/Networking/Namespace (Workload) Grafana dashboard fails to load. The red error icon that appears indicates there are multiple errors. When I click on it for details, it reports several instances of the error "multiple matches for labels: many-to-one matching must be explicit (group_left/group_right)". See screenshot below.

This is very similar to an earlier problem #951 which was fixed. I suspect this one table was simply missed when the other dashboards were fixed.

@jkroepke: Is it possible you missed this table? I assume (hope) the fix would be straightforward based on the other changes you made.

I deployed the mix-ins as part of deploying the Kube-Prometheus-Stack Helm chart. I am deploying Kube-Prometheus-Stack Helm chart version 62.7.0 which appears to deploy the mix-ins from this project from commit '50150c585ebee6e4d9cb72218182da8f3c616515'. This appears to be the most current commit (as of the time I'm posting this) and, therefore, should include the fix from #951.

Please provide any helpful snippets.

Yes, I miss that.
