Main Release- Forge Shaders don't render DH Chunks

On the main 2.0 build (2.0.0-a - 1.20.1), any shaders (Tried BSL, Sildurs, Vanilla), prevent DH chunks from rendering at all. The newest nightly build fixes this, but has no shading. I'm using Forge 47.1.43, Optifine 1.20.1_HD_U_I6_pre6. Apologies if this is known, didn't see it in Gitlab
