At a glance

A division must contain at least 2 subgroups to make sense.

What causes this error

A division splits a class group into two or more subgroups that can be scheduled independently. A division with only one subgroup has no purpose and cannot be scheduled correctly.

How to fix it

Go to the Divisions section, find the division for the affected group, and add at least one more subgroup. If you no longer need this division, delete it entirely.
