Description of problem:

checked on 4.19.0-0.nightly-2025-09-19-111328/4.20.0-0.nightly-2025-09-19-231410/4.21.0-0.nightly-2025-09-19-012417, admin user goes to "Observe -> Dashboards", "API Performance" is the default dashboards, select etcd dashboard then select "Kubernetes / Compute Resources / Cluster" dashboard, No datapoints found for the graph.

if we click other memu, example "Observe -> Alerting" first, then click "Observe -> Dashboards", select "Kubernetes / Compute Resources / Cluster" dashboard directly, will see the result for the graphs. see recording: https://drive.google.com/file/d/1jt6XNNIeoHFpMSuD-H5kB3Hkezmx1PzH/view?usp=drive_link

4.18 does not have such issue, compared with 4.18.0-0.nightly-2025-09-21-213014

for 4.18.0-0.nightly-2025-09-21-213014, dashboards url are

API Performance: https://<console_url>/monitoring/dashboards/grafana-dashboard-apiserver-performance?period=5m&apiserver=kube-apiserver
etcd: https://<console_url>/monitoring/dashboards/etcd-dashboard?cluster=etcd
Kubernetes / Compute Resources / Cluster: https://<console_url>/monitoring/dashboards/dashboard-k8s-resources-cluster

4.19+

API Performance:https://<console_url>/monitoring/dashboards/grafana-dashboard-apiserver-performance?timeRange=1800000&period=5m&apiserver=kube-apiserver

etcd: https://<console_url>/monitoring/dashboards/etcd-dashboard?timeRange=1800000&period=5m&apiserver=kube-apiserver&cluster=etcd
Kubernetes / Compute Resources / Cluster: https://<console_url>/monitoring/dashboards/dashboard-k8s-resources-cluster?timeRange=1800000&period=5m&apiserver=kube-apiserver&cluster=etcd

we can find out the 4.19+ dashboards carry the parameters from the previous dashboard, then append its dashboard parameters, this could cause the No datapoints found for the graph

Version-Release number of selected component (if applicable):

4.19+

How reproducible:

always

Steps to Reproduce:

1. see the description

Actual results:

"Observe - Dashboards" dashboards carry the parameters from the previous dashboard caused no datapoints found for the graph 

Expected results:

show result for graph
