For class 9A, there are lessons from the same division, with different weekly frequency: GER - 3 lessons, FRE - 2 lessons. Correct the data so that lessons of the same division have the same weekly frequency (same number of lessons).
Let’s say a class is split into two subgroups for beginner language lessons: one learns French, the other German. These lessons are meant to take place at the same time.
If the German group has 3 weekly lessons, the French group must also have 3.
If French is configured with only 2 weekly lessons, the German group ends up with one extra lesson, causing an imbalance — which is not supported.
Go to the lessons section, search for the class mentioned in the error message, and make sure all lessons within the same division have the same weekly frequency.
