[ARCHIVED] How do I modify which assignments are listed in the course summary if the course summary is listing more assignments than I have?

[mnuar]

This is dealing with the course summary at the end of the syllabus. Every past date the assignment was due is listed in the course summary, so I have the same assignment listed 4 times right now, from 2016 to present.  But it is not like I have that many different assignments. If I enter the assignments section, each is listed just once. I am unsure of what I should be changing so that each assignment only shows up once in the course summary with the correct due date.

Thanks for any suggestions,
