How do i randomly distribute biomes? (in custom dimension)

I have a 1.19.2 forge mod in mcreator 2023.4 and a custom dimension with 6 biomes.

I am having trouble making the biomes evenly distribute in generation. It seems no matter what I do to the generation settings, one or two biomes are always dominant while others just don't generate at all.

Does anyone know how to achieve an even distribution of my 6 biomes inside of my custom dimension?

Any and ALL input is highly appreciated.

Thanks.
