New Quiz shows as ungraded even after grading both questions

[KateAllen1]

I am trying to grade a quiz that has one multiple choice question and one essay question. The essay question is worth zero points because it is optional. When I try to grade the zero point question, it says that it updates the score (which stays the same since it's zero points), but the ungraded icon stays and the student's overall grade still does not incorporate the quiz score. Help? I tried overriding the quiz score on the Grades page but it didn't work.

Hi Kate, 

Thank you for reaching out. I'm sorry to hear you're experiencing this issue. However, for an issue like this, it sounds like everything should be working properly, and this would most likely be something Canvas support will want to investigate. Please reach out to them, and you can do so via the "help" menu on the left hand column in Canvas.
