Group Manager not detecting worlds?

So I just got Group Manager for my server, I Start it up with no errors or problems. I Check the Group manager folder, i check my worlds and all i see is "superhostile" Which is my main survival world and "World" I don't even have a world name "World". So I need 3 more worlds added into group manager. My Nether world, End World and Creative World. My Question is how do i add more worlds for group manager?

 

It depends exactly what you want to do. Simplest is to "mirror" your main world into all the others. See:

by default groupmanager tries to mirror all worlds to master world "world", however since your main world is "superhostile" it cant mirror it to "world" thus you have 2 world folders.
