Old Rules Appearing in Profile

I have been updating some profiles which were orginally generated using the Profile by Slope form Element tool. The original plan elements have been joined together to form complex geometry before the old vertical alignment associated with the individual elements was deleted. Thus there are areas where the old profile appears, see the green dashed lines circeled in red in the screenshot. I cannot delete the old profiles because ORD thinks that no elements are selected. This is also the case if I use Drop Element or Drop Complex Status. The only way that I have been able to delete the old vertical profiles is to drop the new complex plan geometry and deleting vertical profiles associated with the individual plan elements. This is a time consuming process!

Is there a way to get rid of the old vertical geometry associated with the components that have been used to make the new plan complex geometry?
