I am a new server owner and I am having trouble with permissions. I am following what the "permissions" tab says to do, but it is not working. 

What I typed:
oxide.grant admin nteleportation.deletehome


What is says to type 
oxide.grant <user or group> <name or steam id> <permission>

Which is exactly what i did. This is happening for every permission nteleportation lists. I can't get any of them to work. Please help! what am I doing wrong?

try this oxide.grant group admin nteleportation.deletehome
