Sides of Grass Blocks are wrong shade of Green in Cherry Grove Biomes

The sides of grass blocks seem to be the wrong shade of green in Cherry Grove Biomes in the new update. I have attached an image of this phenomenon in both the Release and Preview. It seems only to affect the sides of the grass blocks the top rather being a different shade. I had no texture packs on either version when I documented this; only the vanilla texture pack. It does affect all sides and is not directional. Duplicate. Original is MCPE-168200
