Plugin Help Having trouble with PEX

Well i got a hub (name = Fallen)
and i have 3 different multiverses with the multiverse core and portals.
Now i don't want people to be able to break blocks in the hub, and also not use the command /island to join the island from the hub but go through the Skyblock portal first, this doesn't seem to be working for me.
1. i can't use portals
2.i can still use /island
3.i cant break blocks in my own island or any other server.

this is my code:

Code:

groups:
  default:
    options:
      default: true
    permissions:
    - modifyworld.*
    - multiverse.teleport.self.NAME
    worlds:
      Fallen:
      - modifyworld.chat
      - -modifyworld.*
      - -askyblock.*
      - multiverse.teleport.self.NAME
      Survival:
      - modifyworld.*
      - -askyblock.*
      - multiverse.teleport.self.NAME
      ASkyblock:
      - modifyworld.*
      - askyblock.island.*
      - askyblock.team.create
      - askyblock.team.kick
      - askyblock.team.makeleader
      - askyblock.team.join
      - askyblock.coop
      - multiverse.teleport.self.NAME
      hide:
      - -askyblock.*
      - multiverse.teleport.self.NAME
