essentials.teleport.delay.bypass Not working?

So I have a delay on my server for teleporting and it works perfectly fine, yet I want my Moderators to be able to bypass the delay so they can get to people quick. Since my moderators are not ops, I used the "essentials.teleport.delay.bypass" permissions and added it to a single player's permissions. It doesn't seem to work.
I am using PermissionsBukkit.
Also, is it possible to have all my players bypass the delay for a certain multiverse world?

Thanks,
Regards, Brinaq

 

I don't know how to answer your first question, but for all players bypassing it in one world, do this command:

/permissions group setperm <group> worldname:essentials.teleport.delay.bypass true

And to make sure they don't bypass the delay in another world, do the same command for that other world and change true to false.

 

That's what I did and it doesnt work.

 

please paste your permissions file.
