AlltheMods6-totheSky issues

I am having issues with the all the mods 6 to the sky mod pack, when I join the world after the server is running, it does not spawn me on a skyblock, it spawns me on a regularly generated default world

This should be fixed if you reinstall your server in the options

I just made a single player world and copied the world onto my server but thank you for the option
