Late submission even when available until date is set?

Community Member


I have a quiz with a due date set to 3/22/23 at 10 am and the same for the available until date. The quiz time limit is 2 hours. I was under the impression that the student quiz would be automatically submitted at the available until date. However, I saw that several students have late submission after the 10 am deadline. 

Does setting the time limit override the available until date? From what I could find, that shouldn't be the case. I attached screen-cap. The student with the late submission is not the same as the one that was given the extension.
