When the minecraft version was 1.19, add-ons worked perfectly fine. The biomes and structures generate naturally. But since 1.20 especially 1.20.60, add-ons' like biome and structure add-ons cant generate any biomes and structures naturally. There I attached 2 images of the same place with the same add-ons, same settings, same seed, and the same place, but different versions. The one with palm trees is the image of my 1.19 world, meanwhile the other image is my new 1.20.60 world

There I have the add-ons that I used in 2 of the worlds. Keep in mind that this bug happens on every add-ons which influences the world's generations.

I tried to download the newest version of the add-ons but still it wont generate any biome or structure, and even the experimental settings are all on except the new 1.21 experimentals. Please fix this bug so I can play those add-ons with my friends again.
