Tall birch tree, shattered savanna, badlands plateau, and dark forest biomes have wrong grass color

Expected behaviour:

Savanna M and Savanna Plateau M should have darkish yellow brown grass. Birch Forest M and Hills M should have the birch forest grass color. Roofed Forest and Roofed Forest M have very very dark green grass color. Mesa Plateau biomes have mesa biome color for the grass foliage.

Actual behaviour:

All 6 biomes have the default grass color which is not right and doesn't match the regular biome. Mesa Plateau is generating desert grass foliage color instead of the mesa color.

Affected biomes:

Steps to reproduce:

Just create a new world and check the M biomes I said, you'll see the grass color is different in the M biome form the regular one.
