Quiz

In a course we erased all enrollments and enrolled new students.

Now the name of some of the old students appears in the list  of attempted quizzes, without a link to the quiz answers(see table  below). I traced the problem to some entries in the table mdl_quiz_attempts. In the dump below the last two lines, with timefinish=0 ,corrsepond to old students.  I suppose that for some reason the entries were not erased when the students have been un-enrolled.

Can I just erase the entries to clean_up?

More annoying is that, after taking the quiz and seeing the results on the screen, some of the new students' attempts do not appear in the list of attemped quizzes and the grades are not recorded. ( I have not been able to replicate this behaviour though) .

Any idea?
