ConceptD CP5271UV monitor keeps switching Light Sensor to OFF all the time.

Hi guys, it is really a simple as that. In my USER profile I set up Light Sensor to ON and save the profile. When I change the profile to anything else AND I come back to my USER profile OR the profile I saved settings to (for example STANDARD), Light Sensor is OFF again and the monitor behaves according to Brightness settings saved. Is there a way to solve this? It is incredibly stupid SW decision by Acer...
