1 - Draw a rectangle, a shape, a circle, whatever;
2 - Copy the rectangle (or your element) to the exact same location;
3 - Change one of the elements to get a fill shape;
4 - Run the Analyze\Design File Cleanup\General\Cleanup Actions with Select mode;
5 - Check the result.
This analyze should take in consideration if the shapes have fill or not which in fact they are different in this propertie.
We should get a positive result if we need two elements, one for the boundary and another for the actual fill.
