Question How to set up Towny prefixes?

I have a bit of an issue here, on our server we cant seem to get the Town tags to work (and oddly enough only when players are unopped) and it's brought us to a halt. For me, it displays my town as I told it to, but for her it simply doesn't. It adds an extra set of []'s to the group prefix, though. It also changes their name to be teal instead of the default gray I set it to be. Pictures and my towny chat config below.

Code:

  # The formats below will specify the changes made to the player chat when talking.
  # These keys can be used in other plugins that modify the chat format like iChat.
  # {worldname} - Displays the world the player is currently in.
  # {town} - Displays town name if a member of a town.
  # {townformatted} - Displays town name (if a member of a town) using tag_format.town.
  # {towntag} - Displays the formated town tag (if a member of a town) using modify_chat.tag_format.town.
  # {towntagoverride} - Displays the formated town tag (if a member of a town and present) or falls back to the full name (using modify_chat.tag_format.town).
  # {nation} - Displays nation name if a member of a nation.
