The last assignment on week 3 shows as pending even though it passed

I have submitted the last assignment of the course multiple times, all passing, but it is not registering as complete, even though it shows as passed. It has a green checkmark next to it, while saying “1 graded assignment left”. Any idea what’s going on here, how do I fix this?

Could the missing assignment be a skipped quiz?

I don’t believe so, they show up as completed. The only one showing up as “1 graded assignment left” is the reinforced learning.

I tried resubmitting in other browsers (firefox originally, then chrome, and finally through my phone) and none of the marked it as submitted, even through there is a passing grade

I contacted the coursera chat, and they advised to clear cookies and resubmit. It seems to have worked.
