Why would a quiz show grades manually overwritten

I ran a short quiz (7 questions) for a class of 450 students. Some questions were multiple choice, some were calculation questions and some were multi-select questions. The latter had 5 possible answers, where each correct selection (or blank) was worth 0.2 points. Students were permitted only a single attempt.

When the quiz was completed used the “Grade” option next to the quiz name and I see that 13 of the 40 students had in indicator next to their overall grade of “manually overwritten”. In the case where the students did not get 7/7, those with the “manually overwritten” indication showed an increase of grade. It's puzzling that even a student who got 7/7 has this indication on it!

Neither of the instructors, nor the TA manually changed the grades. Any clue as to how this happened?

    Sorry, it should say 40 students, not 450 in the first line!

    I could also add that not all students who lost marks on the multi-select questions showed this “manually overwritten” indication (which was why I initially thought this issue arose).

    Can you look at the logs in the quiz and the grade book to see if anyone changed anything? Any quizzes have grades manually changed in either the quiz tool or in grades? Were the maximum points changed on the grade item in the grade book after students took the quiz?

    You can retract the feedback in the quiz to remove the grades from the grade book and then just re-publish them (as long as you know the max points is correct on the grade item). That should fix the overall grade shown in quizzes.

    If nothing shows up in the logs and it's not fixed by retracting/re-publishing, then you might want to submit a support ticket.

    Looking over the students that had this “manually overwritten” grade more carefully, I noted that all had written the quiz before a certain time (less than a week ago). Anyone who wrote the quiz later that day did not have this “manually overwritten” indicator next to their grade. I'm quite sure I didn't edit the questions or change the maximum points for the quiz at that time! To fix the grades I simply went into each of their attempts and clicked the “reset evaluation” button which then correctly re-graded their quiz and corrected the grade in the gradebook.
