error in Buildings.ThermalZones.FLEXLAB example?

edit

Does anyone recognize this error? Is it my computer or a bug? I don't think I changed anything in the example, and I keep getting this error in my own models as well..

what does the error mean? should R16p8Wal be of another type? redeclared?
I don't know if the first line of the error is printed so i recopied it: 
 
Type mismatch in array expression in component X3B. R16p8Wal is of type record Buildings.ThermalZones.Detailed.FLEXLAB.Data.Constructions.OpaqueConstructions.ExteriorConstructions.ExteriorDoorInsulated
