I tried toggling off all the engine settings and also wanted to see what just night would be like. Once I toggled to night I was stuck in darkness. Even changing the settings back to day/night or full day kept the map in darkness. Full restart didn't fix it either. This was on the ice planet.
Day/Night seems to work fine on my Red Planet map though.

On the Zolarg (and LIS) ice world, there is only darkness.
