How to play with a specific group using Ansible Playbook

Question

Possible version: 2.1.0

My file name:

[PM]
asma.example.com ansible_connection=ssh

[ND]
malliswar.example.com ansible_connection=ssh

[CM]
asma.example.com ansible_connection=ssh
malliswar.example.com ansible_connection=ssh

And playbook:

- hosts: PM:ND:CM
   remote_user: root
   tasks:
    {some thing}

- hosts: PM
   remote_user: root
   tasks:
    {some thing}

 - hosts: ND
   remote_user: root
   tasks:
    {some thing}

- hosts: CM
   remote_user: root
   tasks:
    {some thing}

And I run the playbook with the following command:

ansible-playbook --limit 'PM' akana-installation.yml

But still the playbook plays all hosts, that means

Play 'PM:ND:CM'
Play 'PM'
Play 'ND'
Play 'CM'

all games are playing. Please help me solve this problem.

What I need: During the execution of the playbook, I will give the name of the group that only the group should play , so please let me know if there is another way.

The original question: the -limit option does not work

ansible-playbook --limit 'PM' akana-installation.yml, , PM.
asma.example.com.

:

[PM]
asma.example.com ansible_connection=ssh

[ND]

[CM]
asma.example.com ansible_connection=ssh

, asma.example.com.
:

Play 'PM:ND:CM'
[asma.example.com]
Play 'PM'
[asma.example.com]
Play 'ND'
skipping: no hosts matched
Play 'CM'
[asma.example.com]
