Speedgrader default points on a quiz question

Community Member

How do I get Speedgrader to stop assigning the points in essay quiz questions from the last graded student to the next ungraded one? This usually begins around the middle of a quiz, more or less to a student with the last initial of L. It is as if Speedgrader is carrying over the last submitted value to the next student.  I initially thought that this was a browser misbehavior, but went to a great deal of trouble to determine it's not browser autofill.
