Environment - DEV was updated after scaling 2 nodes up / and now scaling down to the former nodepool nodes.

Accured Problem with Product Portal Dashboard, had to manually update the Dashboard. It seem's that Grafana handles the imports differently if you use the API vs the GUI. I imported your dashboad manually via GUI on dev and it seems to work: https://grafana.dev.demo.catena-x.net/d/bd886d0a-492c-47e8-b4a5-b389814598d9/product-portal-2?orgId=1
