Biomes are way too rare

So i made a mod that adds a bunch of biomes. i had to update it to have 1.18 support. sadly when i generated a world to test the biome generation in 1.18. no biome was found in reasonable distance. i was confused. so i decided to turn up the biome weight to 100 (max). and they still didnt spawn in a radius of 2000 blocks. how can i fix this?
