The course requests that appear when you click on the student's name are actually for the current school year. When you click on the student's name, it's taking you to the student's profile, which has no connection to the Approval Worklist (as that is for the upcoming school year)

Once you change the School Year located below the student's name to the upcoming school year you'll see the correct number of Course Requests and they should match the number in the Worklist.
