there is a problem it seems that the configuration has problems.
some blocks cannot be disabled.
I found the problem with Dirtstone is always generated even if I disable it.
I don't know if this problem is repeated in other blocks.
in my world I have only had problems with that block
In addition, the flint continues to be generated very frequently, it is also generated on blocks of ice
