Sky sphere Colors

Hi, I’m using the UE5 plugin Sun positioner with a sky sphere. Sky sphere uses a directional light. When I control the sun to be at night time position everything is too bright/reddish. I discovered that there is a setting for the sky sphere called “Colors determined by Sun Position” and by disabling it I can change night color settings to be more accurate. However when I run the game, the colors are automatically reverted to the same as if that setting was still enabled! I’ve even tried to disable it completely directly from the blueprint but nothing helps. How could I solve this problem?
