Peninsula Corridor - San Francisco to Gilroy

I've noticed that some of the speed limits don't change at the signs or the signs don't show in the HUD. Is there a way to correct this in the route editor? The first scenario when running the gallery car you pass a green maximum authorized speed sign of 79mph but the speed doesn't increase until you are way past the sign. Also when running one of the freight scenarios you pass a 40mph speed sign that doesn't show in the HUD and doesn't change the allowable speed till well past that sign.
