Rancher2 Node Pool on Azure / No Resource Cleanup on Destroy

I’m provisioning a Kubernetes cluster on Azure, using the Rancher2 provider with a node pool, and it works absolutely fine.

However, when I destroy the plan, the Azure resources do not get cleaned up. The destruction of the rancher2_node_pool succeeds within a second, but no actual cleanup on Azure takes place.

Any ideas as to why that is?

Thank you!
