Referencing gint alignments

Hi. I am trying to create a legend for a fence diagram. To do this, I created a polyline with type=By layer, thickness= (blank), and color=By layer. Under the Configuration tab, I've set the override line type, thickness, and color expressions to the corresponding GINT_ALIGNMENTS.Z1 type, thickness, and color. However, when I output, the polyline is displayed with the default properties and not the override properties. Any help would be appreciated. Thank you.
