Overlap of point symbology

I'm having a problem understanding how the overlap of symbology works. I have two separate point shapefiles that denote different types of airports. One airport file (the base) is a light blue circle. On top of that I overlay another airport shapefile (the airports of interest) and that is a pink star. Now when i turn on both layers I would expect those airports that are coincident to have a pink star on top of a blue circle. This is not the case, all I see is a blue dot. My legend shows that definitely the pink star layer is on top of the blue circle layer.

I just tried in the ESRI product and that shows the two symbology even if they are on top of each other. Am I missing something to make that work in MapWindow?
