Missing information when scraping data in grafana using prometheus and minikube - kubernetes

Question

I am trying to use prometheus and grafana to get information like cluster cpu usage, cluster memory usage and pod cpu usage in my kubernetes cluster. I am using minikube in wsl2. I am using following commands to get everything up and running:
To start minikube:
$ minikube start
To add repo and install prometheus:
$ helm repo add prometheus-community https://prometheus-community.github.io/helm-charts
$ helm repo update
$ helm install prometheus prometheus-community/prometheus
To create a nodeport on the port 9090:
$ kubectl expose service prometheus-server --type=NodePort --target-port=9090 --name=prometheus-server-ext
To access prometheus server outside minikube:
$ minikube service prometheus-server-ext
Adding grafana report and installing with helm:
$ helm repo add grafana https://grafana.github.io/helm-charts
$ helm repo update
$ helm install grafana grafana/grafana
To create a nodeport on the port 3000 :
$ kubectl expose service grafana --type=NodePort --target-port=3000 --name=grafana-ext
To access grafana server outside minikube:
$ minikube service grafana-ext
To get decode and get password to grafana(username:admin):
$ kubectl get secret --namespace default grafana -o jsonpath="{.data.admin-password}" | base64 --decode ; echo
Then I add a data source with type prometheus and the URL seen above: https://192.168.49.2:30988.
Until here everything works as expected. Then I import two different dashboards with the id "6417" and "12740". I then get the following dashboards:
and
My question is why do I only see the number of pods and cluster memory usage, but no cpu usage of pods or the cluster? It seems like there is a lot of information missing.
Here is the JSON code for dashboard with id 6417: https://pastebin.com/ywrT2qmQ
Here is the JSON code for dashboard with id 12740: https://pastebin.com/2neEzESu
I get the dashboards by using the id's 6417 and 12740 and importing it. Check image below:
