I'm not sure how easy this is to fix, but...
If you create a master polyline and then create two void polylines and add them to the master polyline, the area is calculated subtracting the area of the two voids from the area of the master polyline. This is fine until you lap the voids on top of each other.
If you hatch the polyline you will see distinct areas of hatch and non-hatch. The area calculation should return a value that represents all areas that are diplaying hatch. It should calculate the overlapping areas of the voids and add this value back into the total area.
