PermissionsEx Help Needed

Hello PlanetMinecrafters!

For a good month, I have been experiencing some difficulties with the PermissionsEx Plugin. Everything is working fine except that whenever someone talks, this appears:

[Spawn][Owner][Owner]7acespade: Hello!

Is there anyway to remove the double owner tag? Thanks a bunch! I would be happy to give the helper an Administrator rank on my server. Heres the code:

groups:
Member:
prefix: '&f[&7Member&f]'
default: true
permissions:

- essentials.
- essentials.kit
- essentials.build
- modifyworld*
- essentials.balance.others
- essentials.balancetop
- essentials.pay

- essentials.tpahere
- essentials.tpaccept
- essentials.tpdeny

Owner:
prefix: '&4[&cOwner&c&4]'
permissions:
- '*'
users:
7acespade:
group:

And Heres The Code For The Config File:

superperms: {}

Thanks A Bunch Guys!
