I have a teacher who suddenly cannot see the student roster in the gradebook. This teacher is currently assigned to teach 3 classes. Each class has two sections. When the teacher accesses courses 1 and 2, they see a drop-down list to see all students or to select a specific section. In the third course when the teacher accesses the gradebook the drop-down option to select multiple sections is not visible, only individual view (screengrab attached). I checked that this teacher assigned to both sections. Is there a reason that they would not be able to select a section or to see all enrollments across all sections?
