Survival Server URGENT SPAWN HELP NEEDED

This is pretty Important!

On my server I use GroupManager, now before you tell me to use PEX , ive tried it and i prefer GroupManager (Idk why).

Anyway, there is a problem with the permissions for people on my server.
On -essentials_default , it has:

g:essentials_default:
permissions:
- essentials.help
- essentials.helpop
- essentials.list
- essentials.motd
- essentials.rules
- essentials.spawn
- groupmanager.notify.self

But, /spawn doesnt work for Default users, even though it is listed here

The other commands work, like /rules /motd /help etc, but not /spawn

The only people who can use it are Owners and OP's, even not people like Builders, Mods or Admins.

Please Help!

Thanks,
Space.
