Has anyone experienced inconsistent “overdue” notices for assignments/quizzes completed on time?

Details:
In one of our courses, we’re seeing a strange issue where a single assignment appears as “overdue” for all students in the Content area, even though every student submitted it before the due date. I impersonated eight different students, and the behavior is identical—only this one assignment shows the overdue message, while all other assignments look normal.

Follow-Up Issue:
We’re now noticing similar behavior with some quizzes:

• The quizzes are auto-graded and published to the gradebook.
• Some quizzes randomly display an “overdue” notice for students who completed attempts well in advance.
• Other quizzes show the correct behavior and simply display the due date.

Ask:
Has anyone else run into this?
If so, did you identify what caused it or find a workaround? Any insight would be greatly appreciated.
