After some investigation and a great hint from HCL in person of Andre Guirard this issue can easily be solved by adding a second alias to the view

You have to add the replace the existing alias “ClusterConfigurations” with the following alias:

ClusterConfigurations|Server\Cluster Configurations

Don´t care, that only the last alias is displayed in the Designer view:

After adding the second alias and replacing the desing everything is running fine with the German LP.
