Copied \ Imported Panel shows no data

Hi,

We have a few Prometheus dashboards and I would like to show selected panels from these dashboards in one, centralized, dashboard.
I’ve tried copying the panel (panel menu > more > copy), importing the panel’s json (panel menu > inspect > panel json), copy part of the dashboard json…
All methods resulted in a perfectly copied panel, without the data.
I’ve checked that the configuration is copied correctly, see panel comparison screenshots.
Original panel config


Copied\imported panel config:

I’ve added the variables from the original dashboard:

We’re using Grafana 7.2.1 deployed over an AKS cluster.

Any solution\ advice\ direction would be much appreciated!
