OpenStudio ignores daylight controls when using Radiance measure

Hi all. I am simulating a room with a window for calculating an illuminance map with daylighing Control on OpenStudio. I added a Radiance Measure in OS and ran the model. The Problem is that as i add the Radiance Measure, the OpenSturio deletes the daylighting controls and the results is as when I have no daylighing control!!! I do not know where is the problem with that. I appreciate whoever can help!

The function of the Radiance measure is to handle daylighting in place of EnergyPlus. After Radiance performs daylighting, it adjusts the lighting schedules to reflect how much daylighting is available and adjusts the lighting schedule downward. It then deletes the daylighting control so you are not double counting both engines daylighting, and then runs EnergyPlus without daylighting controls. To test if and how it is impacting, I would suggest comparing results without the measure and with the measure applied, and without the measure but with no E+ daylighting as baseline.

Thanks, @David Goldwasser for the reply. I test the models. The baseline and the model with DL control and with the Radiance measure have the same results (same lighting electricity outputs). I wonder why it should be like that?
