Probuilder Bezier Shape, No initial curve with controllpoints/tangents

Hi, im trying to create a bezier shape with the experimental probuilder tool. When I click "New Bezier Shape" I dont get any initial curve with controllpoints and tangent handles. Im able to do some adjustments when I click "Edit Bezier Shape" in the inspector, but it is har to see what im doing without the initial green curve in the center of the object, see screenshot. You can see the green curve when he creates the shape in the video from 2017.
Mine:


His: See the green curve in senter

 

I had the same issue turns out there is a setting in main Preferences window -> Probuilder -> Experimental Features enabled.
Note that it takes a while to take effect and you may need to have a particular build target set see https://forum.unity.com/threads/probuilder-how-to-boolean-subtract-object-from-another.829515/ for more details

 

check Gizmos in Scene View
