Groupmanager mirroring help!!

Hey, ive tried to get this mirroring to work. but it seems like it wont (hehe) im not the best at this stuff, so decided to ask for some help here.

Config:
mirrors:
# Worlds listed here have their settings mirrored in their children.
# The first element 'world' is the main worlds name
# subsequent elements 'world_nether' and 'world_the_end' are worlds which will use
# the same user/groups files as the parent.
# Each child world can be configured to mirror the 'groups', 'users' or both files from it's parent.
spawnworld:
spawnworld_nether:
- users
- groups
spawnworld_the_end:
- users
- groups
towny:
- users
- groups
factions:
- users
- groups
Shop
- users
- groups
# world2: (World2 would have it's own set of user and groups files)
# 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) from world5)

This particular error is SO CLEARLY STATED by the error message

Shop
^
could not found expected ':'

Translation: "In line 42, Column 11... Where this block "Shop" is, the parser can not find the colin after the name that it is expecting.
