Cannot enter grade - blocked

In my grade book, quiz section, there are some blocks filled with gray (not gray with lines) where I am unable to input a grade of zero.  How can I remove the gray in order to add a grade of zero (the student did not take the quiz)?

Thank you.

Hello,  @pohlmar ​, and welcome to the Canvas Community! Is your school using multiple grading periods--and if so, does the due date for the quiz fall in a grading period that has already closed? Please refer to Canvas Release: Close Dates for Grading Periods​ for more information about this.

If not, has the course been concluded (check under the course Settings tab to see the end date for the course)? If that's the case, and you're not able to change the end date for the course, please contact your Canvas admin to get the course reopened for teacher grade input. The process for changing end dates is described in How do I change the start and end dates for a course?

And if neither of these is the issue, your best next course of action will be to start a support case so that Canvas Support can have a look at your Gradebook (How do I get help with Canvas?​).

Hi there,

We ran into some of these grey blocks too - was the quiz assigned to everyone in your course? (How do I assign a quiz to a course section? )

Finding out the quiz wasn't assigned to the student resolved the grey blocks in our situation.

It's just something else to check,
