Grade item is not calculated. The multiplicator doesn't work

Hi all! I have faced difficulties with the Gradebook. Please, help.
What I need: I have a course which end date has already expired. The course contains one quiz. I need to multiply grader report column (grade item) to a fixed number (0.6).
1) My first attempt was to use a Multiplicator field of the quiz grade item. But the grader report isn't updated after I change the Multiplicator from 1.0000 to 0.6666.
2) Also I tried to create new grade item and set it's calculation to "=Origin*0.6". I have set the "Origin" ID for the quiz grade item. But the new grade item isn't calculated at all - it just shows me a dash in every row. So, I see two grade items at the gradebook - the quiz grade item which is filled with original scores and a second column of dashes. New grade items are not calculated at all even if I set the calculation to "=1".
What did I miss? How to update the grader report? Thanks!
