AOL: error in user's score
I'm using AOL for a client's project.
The course has a final assessment with passing score 80%.
The following user (Richiello) is reported as imcomplete with score 0% (see image below) while the detail of his answers for the 10 questions is 70% - 7 right answers and 3 wrong answers (see attached pdf file).
How is this possible?
