Retrieve clear all attempts!

Hi Jetmir,

I had unhid a column I had incorrectly graded as I wanted to return it to its original grades the system had generated. After I unhid the column, as began browsing through the secondary options. Then by mistake I let go of my mouse on the last option which was to clear all attempts by the users. Now it appears that majority of the grades are missing. When I enter a student's profile there seems to be nothing in there.
