When you create a secondary model with the Model Creator Node, and assign units to the output of the model (e.g. Output=Dvalue;units= h), then this unit disappears when the Secondary Model View or the Secondary Predictor View nodes are used.
(Attached workflow)
the model creator outputs the unit correctly. can you please look on the SecondaryPredictorView?
Units for secondary depVars should now appear in SecondaryModelView/SecondaryPredictorView
