Biome You'll Go removed biome still load in terraforged

[Fyzii]

do you know how to remove some biome from byg in an terraforged word because i try to put -1 and 0 in the config of byg but there is still those fantaisy bad biome in my terraforged world
byg = biome you'll go
and im on 1.16.5

This is not an issue with Byg but with terraforged because on normal world those biome are removed
