Rebuild Classes to Send
Now that a new year's timetable has been enabled the option to rebuild the class list should be enabled and run so as to remove any class that has been copied over from last years timetable.
This is to stop redundant classes from being sent to the LMS.
To rebuild your class list, check the box at the bottom of the Setup → KAMAR → Server → LMS → Class Membership tab.
This checkbox will automatically clear itself once run.
