Ansible AWX issue when running playbook from WebGUI

Question

I have recently configured Ansible AWX, the hosts file on /etc/ansible is populated by two server groups:

[ovirtmanager]

10.0.0.10

[ovirthv]

10.0.0.100
10.0.0.101

Via CLI my playbook called check-service-status.yml runs correctly

---
- hosts: ovirthv
  become: no
  gather_facts: yes
  tasks:
  - name: "Populate service facts"
    service_facts:
  - name: "See if the service <lldpad> is up and running"
    debug:
      msg: "{{ansible_facts.services['lldpad.service'].state}}"
  - name: "See if the service <fcoe> is up and running"
    debug:
      msg: "{{ansible_facts.services['fcoe.service'].state}}"

Using the WebGUI I get this message:

[WARNING]: Could not match supplied host pattern, ignoring: ovirthv
PLAY [ovirthv] *****************************************************************
skipping: no hosts matched
PLAY RECAP *********************************************************************

How can I solve this problem? What's wrong? Thank you very much!

UPDATE: here is the playbook execution via WebGUI
