Whoever told you that was wrong. I can see how this could be a little confusing. The Capstone does not count towards the 18cr of computer science electives required, but it does count towards the 18cr of UL courses required in the Area of Study (AOS).
You can see this below where the UL requirement is not stated inside Part C, but is in it's own section, meaning the UL credits can come from anywhere in the whole AOS.
