SolidWorks bug: segmented/polyline export for sketch curves.

When exporting to .dxf SolidWorks correctly exports the curved edges of solid bodies as curves, and incorrectly exports the curved edges of sketches as segmented/polyline lines.

Figure 1 shows an example of that I'm trying to export to dxf (SolidWorks file attached), Figure 2 shows how this export contains both the correct curved line dxf export (from the solid body), and the incorrect segmented/polyline line export (from the sketch) despite those being the same lines line SolidWorks.

If there is a magic setting regarding how sketches render in drawings that would fix this... I haven't been able to find it. I am using the export splines as splines setting (figure 3).

I'm on laptop, windows 10 build 19043, SolidWorks 2019 service pack 5.0
