Thank you so much, Stephanie! I called Canvas support today and learned what my (and my students') issue was. When setting up the "Complete All Items" module requirement, I had not added every one of the items in the module to that list. I had assumed that checking "complete all items" meant that all items would be required. Now I understand how to use this feature properly, and I understand it is set up this way because an instructor may not want to require every item in the module. Each item must be added manually, and I needed to pull open the window to see the list of the items. See the images below. The first was before I expanded it, and in the second you can see the items as well as "+Add requirement" at the bottom.
