Wrong Nether biome Generation in snapshot 21w37a

In the following image files we can see how the Crimson Forest and Warped forrest biomes n the Nether don´t generate correctly, we can only see a few nether wart block in the crimson forestand a few warped vines in the warped forest, Soulsand valley not generate any soulsand or soulsoil.

 

Also i found a perfectly generated Bastion Remnant inside one buged Warped Forest
