@Johann_P The running order for the rules is reverse logic (or it used to be), so the top of the list is processed last and the bottom first 🙄. So if the upper two could include the column they would take priority. But from what you describe that may not be the case. I am guessing the remaining shapes are empty voids. If you apply a Fill so there are no gaps in the Complex Profile by using the standard "Air Space" Building Material then the "skins" should disappear.
