Marks for quiz missing in user grade report but attempt present
 

Using moodle 2.3.2 (2012062502.00).

A student has taken a quiz, there is a record of an attempt which was successfully finished;

Yet in user report on that student the quiz is shown having no mark (as if not taken);

User grade report: (/course/user.php?mode=grade&id=XYZ&user=XYZ):

 

And when clicked on link that leads to attempt review: (/mod/quiz/grade.php?id=XYZ&itemnumber=0&userid=XYZ that redirects to /mod/quiz/review.php?attempt=XYZ)

 

What can be the reason ?
