I am having challenges with my gradebook for a course.  I have an assignment that is not due for another 5 weeks, but it is showing up in the gradebook as a zero points score, which is taking most of my student's grades to a C or lower.  I have tried removing the assignment and reloading it, checking the due dates, etc.   Normally when an assignment is not due yet in Canvas there is a - (dash) instead of a zero.

No students have uploaded work for this assignment yet.  What can I do?

Many thanks for your help. Lauren Hickman
