HB Daylight Control Schedule / no effective ill set point

Hello friends
I do not know why set point illuminance does not affect fractions. Definitely a set of 50 lux should make a significant change in the lighting schedule compared to the set of 500 lux. But no change is visible.
Does anyone know?
