2023 MERCEDES-BENZ SPRINTER 2500 Visibilitywiper Problems

So I bought a brand new 2023 Mercedes Sprinter Build by Airstream Interstate 19. The front windshield visibility is very bad at night driving. The whole front of windshield has zig zag lines all over the glass for defrosting but those lines make on coming traffic lights very blurry. Driving during day time is normal. Driving during night time all lights look blurry, its kind of like driving with -2 or -3 prescription when looking out the windshield. I called airstream and they said windshield is part of mercedes item. I called mercedes knoxville and they said they have not heard anything like this before.
