Error when using LocalEnvironment objects with airflow network - why?

Hello, I am trying to use the LocalEnvironment objects (both the SurfaceProperty:SurroundingSurfaces and the ZoneProperty:LocalEnvironment) to change the outdoor boundary conditions (air temperature, wind speed and surrounding surface temperature) of specific thermal zones of a naturally ventilated building modelled with the Airflownetwork.

I've used EnergyPlus example idf files for reference. However, after adding the LocalEnvironment objects, I have this kind of sever error with the Airflow-network: The entered number of external nodes is 22. The entered number of external surfaces is 18 This happens even though I don't add any node to the airflow-network.

Anyone has a possible explanation or happen to have the same problem?

Thank you!
