Control polygons

Hi all

Following the transition from SW 2016 to SW 2019 SP3.0, I have a display problem

Indeed, unlike before (on 2016), I see the control polygons when I edit my sketches (see photo)

2 things:

1) the box is unchecked in  : "System Options / Sketch / Show the default spline control polygon"

2) I see these control polygons only on the old splines made with SW 2016 and not on new ones (with SW 2019)

Thank you for your feedback/remarks in advance
