Moodle version 4.1.5
I have a couple of courses where the instructor wants to drop the lowest grade. We use natural aggregation for the top category (course) and subcategories (assignments, test...) All the rules that apply to dropping the lowest grade are correct in these courses. The option is still greyed out. If I change the aggregation back to weighted mean of grade for the top category and simple weighted mean to the subcategories the option is available again. Does anyone know if this is a bug
