Weird sun shadow bug in DH terrain

Hey, i managed to get DH + Shaders to work but I think one of the shaders settings got screwed, I can see the sun shadow through mountains in the distance (DH terrain) But when I'm close it's like normal. The grey box in the picture is where the sun is, when it rises it's normal. I'm using better adventures+ modpack that was meant to work with distant horizons and bliss shaders, any clues to fixing this would be appreciated.
