One Azure cluster, three node created, but why have two primordial storage pools. One is IsClustered One is not IsClustered

here is the output of an S2D Cluster-Node:

Start by reproducing the output from Get-IcingaWindowsInformation with ClassName MSFT_StoragePool in the Root/Microsoft/Windows/Storage namespace. Compare how the plugin represents the two Primordial pools and the S2D pool, focusing on IsPrimordial and IsClustered. Done means establishing whether the duplicate pools are expected and, if not, identifying the concrete correction needed.
