Toolpath preview issues

[Comchinator (Andrew Comchi)]

Hi,
Newbie here. When I create a toolpath for my vector and preview it in 3D I notice that it creates extra stop points. See red arrows in photo. I dont see any vectors in my 2D drawing. Can anyone tell me why?

see attached screenshots

Thanks

Thanks I figured out I had open vectors.
