Ansible issues

Hey folks, Ansible is messing me around. I've got a load of nested defaults that are setup in <role>/defaults/main.yml as follows:

aaa:
  accounts:
    min_uid: 1000
    max_uid: 60000
    min_system_uid: 500
    max_system_uid: 999
    encryption_method: SHA512
  console:
    consoles: '/etc/console'
    su_path:  'PATH=/usr/local/sbin:/usr/local/bin:/usr/bin'
    env_path: 'PATH=/usr/local/sbin:/usr/local/bin:/usr/bin'
    tty_group: tty
    tty_perm:  0600
    erase_character: 0117
    kill_character:  025
    umask: 0027
    motd_path: '/etc/motd'

and I'm using them in a template like this:

## Login Defaults

#### Account-related Settings
UID_MIN			    {{ aaa.accounts.min_uid }}
UID_MAX			    {{ aaa.accounts.max_uid }}
SYS_UID_MIN		    {{ aaa.accounts.min_system_uid }}
SYS_UID_MAX		    {{ aaa.accounts.max_system_uid }}
ENCRYPT_METHOD	    {{ aaa.accounts.encryption_method }}

#### Console-related Settings
CONSOLE             {{ aaa.console.consoles }} 
ENV_SUPATH          {{ aaa.console.su_path }}
ENV_PATH            {{ aaa.console.env_path }}
TTYGROUP            {{ aaa.console.tty_group }}
TTYPERM             {{ aaa.console.tty_perm }}
ERASECHAR           {{ aaa.console.erase_character }}
KILLCHAR            {{ aaa.console.kill_character }}
UMASK               {{ aaa.console.umask }}
MOTD_FILE           {{ aaa.console.motd_path }}

but the numbers are rendering differently:

#### Account-related Settings
UID_MIN                     1000
UID_MAX                     60000
SYS_UID_MIN                 500
SYS_UID_MAX                 999
ENCRYPT_METHOD      SHA512

#### Console-related Settings
CONSOLE             /etc/console
ENV_SUPATH          PATH=/usr/local/sbin:/usr/local/bin:/usr/bin
ENV_PATH            PATH=/usr/local/sbin:/usr/local/bin:/usr/bin
TTYGROUP            tty
TTYPERM             384 # this is not the number I was expecting
ERASECHAR           79  # neither is this
KILLCHAR            21 # nor this
UMASK               23   # or this...
MOTD_FILE           /etc/motd

Weirdly, it's not all the numbers, just some of them, has anyone seen this before?
