How to tied two class with one year group

Hi Ross,

This year, we have two classes of Grade 7, A and B.
When i go to managed time table, I can only tied Grade 7A to Year 7 Group, for 7B i can not tied it to Year 7 as it is already use by 7A.
Should i create another year 7 group to tied it with 7B?

Here is the link, you will see in colom 7B time table the year groups still empty. Admin/tt.php&gibbonSchoolYearID=022
