Prometheus query duplicates values

I ran the query below in Prometheus and I see that it works, however I have 1 pod called dummy-podX not 2 , it seems that somehow the values are being duplicated.

sum by (namespace,pod) (kube_pod_info{namespace="default"})


{namespace="default", pod="dummy-pod3"} 2

{namespace="default", pod="dummy-pod2"} 2

kubectl get pod -n default
NAME                                             READY   STATUS             RESTARTS         AGE
dummy-pod2                                       1/1     Running            0                3h8m
dummy-pod3                                       1/1     Running            0                3h3m

Have you faced this issue?, Is anybody able to advise how to adjust this?.
