Sum-query: Why is a Timeseries and also an Instant returned?

[mandraenke]

Hi, I am trying to count namespaces on a k8s cluster which have running pods (not the number of pods itself).

sum(count(count by(namespace) (kube_pod_info{namespace=~"^project-.*$", instance="project-prod-k8s:9090"}))) by (count)

This works quite well - but the query returns rows as well as an instant (for the last value) and so I have two entries in my graph:

What is the (maybe total obvious) mistake here?

Thanks in advance,
Jan

You didn’t provide reproducible example, so this is just guess : because it is configured:
