I set it back to 0 and it still doesn't work. When I disabled all the grabber options I tested it again and for a bit it showed the test lighting. Unfortunately, I'm unable to reproduce this again. When I press on Start button It clears the LEDs if they were on before and then it doesn't do anything.
