Ansible Tower / AWX No playbooks visible in template

One of my playbooks was not visible in Ansible Tower / AWX.
The troubleshooting steps I have taken to solve the error:

Check if your SCM Sync job was successful.
If yes, take a look in your projects folder in AWX_TASK.
Connect with docker exec to your container, like:

docker exec -i -t awx_task /bin/bash
ls -l /var/lib/awx/projects/

1 2	docker exec -i -t awx_task /bin/bash ls -l /var/lib/awx/projects/

Everything in there should have the correct .yaml or .yml extension.
Your files will not be available if the path contains: roles, tasks, group_vars or host_vars
Check if your playbook contains hosts, like this example:

- name: PreChecks
  hosts: all

1 2	- name: PreChecks hosts: all

Still no playbooks available? Check your hierarchy try to move the playbooks to the root folder in git. Just to be sure..
