I am a course designer in one of the courses I just made and I can't make any edits to a student's grade in the gradebook. I have also added my coworker to the course as a designer and they can go in and add and edit grades.
Why can't I edit grades? Both of us are course designers and only course designers and we used the same methods to enter the gradebook. The only difference is I created the course.
I have used different browsers as well without any success.
