Having issue with loki dashboard the rest of the namespace is showing logs but only 1 specific namespace showing no data

I have a dashboard for loki which i have variables for cluster, namespace, pods and containers.

everything is working fine it’s just that when you choose for the cluster = prod and under the namespace = workflow-services it does not show any data.

also when you go to the explore of grapana and query the cluster name and the namespace the workflow-services does not appear in the list.
