Multiple instances of the marking columns are listed on the Grades tab of student records who have grades listed. The additional or duplicate sets of marking columns have extra sub-header columns listed. For example, the additional columns: Grade ID, Grades Item Data, Translation ID, Values Allowed, Award Credit In, Course Average Calculation, FullComment, and CommentRTF are listed under each additional marking column. The first set of marking columns listed are normal. This does not affect the Grades module (Enter grades by Student) or transcripts/ report cards.
