My teachers have the wrong class lists for attendance today. We have a two day cycle, A and B days and they have the wrong day's list. How do I fix this?

You have the wrong cycle day set on the school calendar. Go to Attendance> Maintenance> Calendar Maintenance and click on today's date. Change the cycle day to the correct day and submit. If you need to recalculate future days, check of the box prior to submitting. This will change future days in the cycle order determined by the cycle day you set today.
