kube-state-metrics exports unexpected labels

I've installed kube-state-metrics v2.3.0 on my k8s cluster (v1.20.7)

When I got the metrics kube_pod_* from kube-state-metrics, the metrics labels are different from the expected.

I expected below

but I got

The label "pod" has the name of "kube-state-metrics" pod not the target pod.

The label "exported_pod" has the name of the target pod.

How can I change the label "exported_pod" to "pod"?
