Print width/lineweight not displaying

I have Make2D lines now in the layout viewport and I see my dashed linetypes but the lineweights are not displaying no matter how much I change them. I tried printdisplay and state=on but still no change. I also have adjusted the print width and layout print width and neither change anything.

Hi Hannah -
Please post a (simplified) 3dm file and the outcome of the Rhino SystemInfo command.
