I have a KML file that is themed with icons according to the values in some attribute. When I add it to ArcGIS Portal 10.3 the legend correctly shows a list of the icons but does not have the attribute value. Rather, it has some number. This number is NOT the number of features for that value, I don't know what it is. Is it possible to have the legend display the value for the attribute which the KML is themed on?
