  • Convert the rectangle to a curve (CTRL+Q, or...Object menu>Convert to Curve). I know that sounds strange, but essentially when you are drawing with any of the shape tools (Ellipse, Rectangle, etc.) you remain in "shape mode" until you convert the object to curves. What you are seeing on the Property bar is corner shaping, which is only available when you are in "shape mode."
