I am loading a csv line file with a column named "GM_Type". In the Generic ASCII dialogue box, "Assign Loaded Line Features the Classification" I have to choose either an Unknown Line Type or one of the line types. This appears to override the type selected in the GM_Type attribute value, and the Feature Information dialogue box shows "GM_TYPE as "Unknown Line Type, State Highway". I am not sure why it shows both, but it renders as Unknown Line Type instead of the intended State Highway. Am I missing something?
