It happens with all texture packs for some reason. If these blocks are far from you, their sides become weirdly dark, but the blocks, which are near you look fine.
This is actually a problem with Legacy Mipmaps conflicting with Sodium. If it's bugging you at all, then I would suggest turning off Legacy Mipmaps for now.
