Make sure you go to each section and add students if you cannot see them in the seating chart.
You will see a yellow box by the edit button if there are students not in the seating chart.
You will see that you have unassigned students listed on the lower right hand corner of your screen. This is the reason why you cannot see them in your seating chart.
Click and drag the student to an empty space within the seating chart.
If you do not have an empty space, change your seating chart dimensions to allow for additional seats. You can do this by clicking on the + button or dragging bar above or next to the seating chart dimensions.
Once you have enough spaces to seat all students, Click “Fill Alpha” and Save.
You are now done seating students in this section.
