When flying around the nether, Soulsand just doesn't exist, no matter where i go, the Soulsand valley biome is completely devoid of soulsand (image will be provided)

Crimson forests do not generate, and are completely devoid of trees, even though the biome marker itself does generate (Images will be provided)

Warped forests do not exist just like the other two, The only thing that generates in is the vines that should be attached to trees (Images will be provided)

I put this all in the same report, as it is a combined issue (Nether biome generations) The nether wastes and Basalt Delta work somewhat though are missing a few usual generations in the world i had, such as those basalt pillar structures with the carved basalt things on them.
