@staylor98 ...
In addition to the information from @chriscas, those three "Assignments" columns look like they might be Assignment Groups on your "Assignments" index page...all with the name "Assignments". I'm not sure how you have your assignments organized in your course...for example, if you are weighting grades or organizing assignments by type such as quizzes, written work, etc. However, having three Assignment Groups each called "Assignments" might be a bit confusing for you and your students. You might consider re-naming those ... or moving assignments into just one Assignment Group if you're not using any kind of weighting or are not separating out the assignments by type. Just a suggestion to make things a bit more organized for everyone involved. Hope this helps a bit.
