Data Source Parent Error

I set up some data sources in Mirth Results. I'm able to process messages from these data sources using Mirth Connect and Mirth Results. Once I set the Data Source Parent, the messages error with the following error. Does anyone know exactly what the Data Source Parent does and why setting it would cause messages not to process?



FACILITY_DOES_NOT_EXIST: com.mirth.results.exceptions.notfound.FacilityNotF oundException: Could not find source facility! ID: FacilityModel{id='DHF', name='null'}
