OpenPlant Modeler CE Update 9 - Cannot search Piping Components

Hi all,

why I cannot search by base class "Piping Component" in Advanced Search in OpenPlant Modeler Connect Update 9? 

In OPM V8i SS6 I was able to do that, so I could find all descendant components like Pipe, Pipe Adapter, Pipe Elbow, etc...with a common property value (example: Service)

Thanks in advance
