[1.20.1]multiverse cannt create right worldtype, its always follow the overworlds' world_type

[tmhxone]

Minecraft Version : Minecraft version 1.20.1 Mohist Version : Provide Mohist build number 695,666,655 the overworld is normal, and I create another flat world where everything works until the server restarts. After restarting the server, the super-flat world becomes normal (created blocks are not affected, uncreated blocks become normal), and vice versa I had the same problem when I tried to create worlds using the “/worlds create" command instead of multiverse

I found that the level.dat configuration of the generator is overwritten by the main world, So the terrain generated error after restart
