We have received a reply from Microsoft. The answer would fit that all non-english operating systems are affected.
With the command "Get-ClusterResource" the cluster resources can be queried.
In german OS there is one role which is called: "Integrität"
In english the role is called: "Health"
Exactly this name (Health) is apparently expected by the GUI. There is a correspondending message also in the cluster logs:
- WARN [API] s_ApiOpenResourceEx: Resource Health not found, status = 5007
Microsoft recommends renaming the ClusterResource to "Health" via Powershell.
