Need help with generating Space

[CoRRupTeD-sHaDow]

I have a problem on my Server that i cant generate a space world.
When i Rightclick the FLOX it creates a new world that should be a world with nothing and some Ores but on my Server it generates a couple chunks without anything besides the Ores but then after some Chunks, it starts generating a normal Minecraft World.
I have the feeling that MultiVerse is doing that Error so i wanted to ask if there is a way to generate it manually or if there is a generator that i can type in the World Creation of MultiVerse?

EDIT: After deleting the World and trying to generate another World i get this Error Message after Right clicking FLOX
