This happens when not all grade levels are mapped between Core and Smart Tuition.This causes a problem when there are Fees or Discounts in Smart Tuition that are tied to those grade levels.  If there are grade levels that your school is no longer using in Smart Tuition and you do not wish to map them to grade levels in Core, you will want to make sure that all your Fees and Discounts are not tied to any of these grade levels before you will be able to map your Discounts to Financial Aid.
