More and more bizarrerer...
Sometimes thae are 12, sometimes they are 11.
I have never used any of the single entry numbers from the drop down list (0-100), only custom scales I wonder how 12 got in there in the first place. It is no recent change. Year after year, weird numbers have always been set for Maximum grade.
Within the grader report, with editing on, clicking on the edit symbol on the top most line (controls), I see Grade Type as scale that I am using, and maximum grade as 11. None can be changed. In Show Advanced, the information is there still cannot be changed.
Clicking on the Edit symbol below that, to get to Edit Grade, There is no indication of scale used or maximum grade.
I can enter a new grade but cannot find an editable option to change the maximum
grade.
