AWX does not delete Host from Inventory

Hello,

I have an problem, but Im not sure if this is an bug or i do it wrong.

I manage my Inventory with an File (calls hosts) in my SCM (GIT). I have specified this file as source of my inventory.
If i add a new host and run the update/sync of the inventory the new host will be added to my inventory.
If I delete an host in my file, the host will not be removed.

I activated the Option “Overwirte”…

Can anyone helps me?

    "analytics_status": "off",
    "version": "1.0.5.31",
    "project_base_dir": "/var/lib/awx/projects",
    "time_zone": "UTC",
    "ansible_version": "2.5.1",
    "project_local_paths": []

If you need more information, please write me.

Best regards,

Marc
