Display mode prints sharp edges - how to stop that?

In Rhino3d version 6 I have custom Technical display mode to hide all but curves. When I print with with this display mode as raster, only curves get printed. However, when I use the same display mode in Rhino 8, it prints not only curves but also sharp edges (interestingly rounded edges are not printed). Why is that and how to fix that?
Attached is my custom display mode.

Hi Mike -

Are you sure you are also printing as raster in Rhino 8?
Are you printing to PDF? Can you provide a 3dm file with samples of the objects that you describe here?

Hi Wim,
It is working now, I think. It must be my laptop memory cache or similar. I think after restarting laptop, it is behaving as expected.
Thanks,
Mike
