In the query form the column name field gets cleared when saving and the following error messages show: Property Label:A Column Heading is blank: 'RH.pyPerformer'. Enter a heading for this column. Property Name: This is not a valid property or this is a property that cannot be used here. See also the attached screenshots. Did anyone else face the same issue? Am i overlooking something?
