Configuration Problème "mirror" Group Manager

[Yhz poi]

Bonjour,
J'ai un problème avec group manager: Le monde "Lobby" n'e rejoins pas le groupe world. Pourtant il est parfaitement écris.
Voci le logs:

[Server thread/WARN] : GroupManager - WARNING - Mirroring error with lobby. Recursive loop detected!

Voici la config:

settings:
  config:
    # With this enabled anyone set as op has full permissions when managing GroupManager
    # The user will be able to promote players to the same group or even above.
    opOverrides: true
   
    # Default setting for 'mantogglevalidate'
    # true will cause GroupManager to attempt name matching by default.
    validate_toggle: true
    # ************************************************************************************************************************************************************
    # *** NOTE: Having this feature enabled can allow improper use of Command Blocks which may lead to undesireable permission changes. You have been warned! ***

    allow_commandblocks: false
   
  data:
    save:
      # How often GroupManager will save it's data back to groups.yml and users.yml
      minutes: 10
      # Number of hours to retain backups (plugins/GroupManager/backup)
      hours: 24
     
  logging:
    # Level of detail GroupManager will use when logging.
    # Acceptable entries are - ALL,CONFIG,FINE,FINER,FINEST,INFO,OFF,SEVERE,WARNING
    level: INFO
   
  mirrors:
        # Worlds listed here have their settings mirrored in their children.
        # The first element 'world' is the main worlds name, and is the parent world.
        # subsequent elements 'world_nether' and 'world_the_end' are worlds which will use
        # the same user/groups files as the parent.
        # the element 'all_unnamed_worlds' specifies all worlds that aren't listed, and automatically mirrors them to it's parent.
        # Each child world can be configured to mirror the 'groups', 'users' or both files from its parent.

    #    world3:
    #    - users    (World3 would use the users.yml from world2, but it's own groups.yml)
    #    world4:
    #    - groups  (World4 would use the groups.yml from world2, but it's own users.yml)
    #  world5:
    #    - world6  (this would cause world6 to mirror both files from world5)

Merci d'avance pour vos réponse.
