The faculty member utilizes "Sum of Grades" as his aggregation type.
He had only entered one grade thus far, so he hid the columns for items containing no grades.
The overall course total changed depending on whether or not the columns were hidden, even though they were all ungraded items - just dashes.
A single exam score of 86 shows the overall course grade as 86 when no grade items are hidden. With hidden grade items, the exam 1 grade still lists 86, but the overall course grade becomes 75.
Any idea why this would happen? Thanks for any leads. See attached file for screenshot.
