Ansible playbook profiling

I’ve tried to enable the following setting in the ansible.cfg, but i’m not getting in play recap any task durations. Am I missing something still ?

[defaults]

callback_enabled = ansible.posix.profile_tasks, ansible.posix.profile_roles, ansible.posix.timer
zzz.xxx.yy          : ok=256  changed=0    unreachable=0    failed=0    skipped=279  rescued=0    ignored=0   

Found the issue, callbacks_enabled instead of callback_enabled i think.
