Every time when superflat preset changed my minecraft always removes any structures and decoration! It generates superflat world without any structures or even decoration which generates only world layers matching the original and biome is the same as original!

I am playing on 1.19.2 Forge because i want to play with Little Logistics mod

I tried checking original 1.19.2 and then going up to 1.20.1 and result was the same even if i moved to vanilla so this is not problem with mods

Note that i am using TLauncher to play MC not official minecraft launcher because i did not bought minecraft.
