My Ore Generation And Biome Generation Is Not Working

When i am working on my mcreator mod, i mostly use stuff like ores and biomes. But when i go into Minecraft to try and use them, they don't work.

Even setting the ores per chunk to the highest amount doesn't work for me.

And when i change the biome weight when it doesn't work, it still doesn't.

I really need help with this as i have spent a very long time on this mod and it hasn't worked.
