Vampire forest from Vampirism mod isn't generate in OTG world

Found this error

Modded biomes do not generate in OTG worlds unless you add your own version to the preset, making use of ReplaceToBiomeName. Alternatively you can use a vanilla overworld and add an OTG world as a dimension using the ‘O’ button in-game.
