At a glance

The maximum value of a rule is set lower than its minimum value.

What causes this error

Scheduling rules come in min/max pairs. This error occurs when the maximum value is set lower than the minimum value, which is a logical contradiction the scheduler cannot resolve.

For example: minimum 5 lessons per day but maximum 3 per day is impossible.

How to fix it

Go to the class configuration rules for the affected group and ensure that the maximum value is greater than or equal to the minimum value.
