Gradebook Visibility

When weighted assignment groups are not enabled, the total column also includes a warning icon notifying you that the grade you see differs from the grade the students see because student grades on one or more graded assignments are hidden.
If an assignment column displays the visibility icon and all cells are grayed out, the assignment is moderated.

To unhide the grade, click on the three stacked dots and then click on Post grades.
