vteps specific entry not added when a global vtep entry exist

[lmaleasi]

Hello,
When a global vtep entry already exist on the switch and that I launch this role with a specific vtep entry to add, the task simply says it's OK and not changed.

Here is a debug output of the configuration passed to the arista.eos-vxlan role:

TASK [eos/eos.vxlan : debug] ***************************************************
ok: [DEV-ARISTA-LMAL-05] => {
    "msg": [
        "ARISTA.EOS-VXLAN config:",
        "vxlan: {'name': 'Vxlan1', 'source_interface': 'Loopback1'}",
        "vteps: [{'vtep': ['10.16.30.1', '10.16.30.2'], 'vlan': 2624}]",
        "vlans: [{'vlanid': 2624, 'name': 'TEST_LIO', 'vni': '2624'}]"
    ]
}
ok: [DEV-ARISTA-LMAL-MAC-SW-WAN-01] => {
    "msg": [
        "ARISTA.EOS-VXLAN config:",
        "vxlan: {'name': 'Vxlan1', 'source_interface': 'Loopback1'}",
        "vteps: [{'vtep': ['10.16.30.2', '10.16.30.3'], 'vlan': 2624}]",
        "vlans: [{'vlanid': 2624, 'name': 'TEST_LIO', 'vni': '2624'}]"
    ]
}
ok: [DEV-ARISTA-LMAL-GEM-SW-WAN-01] => {
    "msg": [
        "ARISTA.EOS-VXLAN config:",
        "vxlan: {'name': 'Vxlan1', 'source_interface': 'Loopback1'}",
        "vteps: [{'vtep': ['10.16.30.1', '10.16.30.3'], 'vlan': 2624}]",
        "vlans: [{'vlanid': 2624, 'name': 'TEST_LIO', 'vni': '2624'}]"
    ]
}

and the output of the vtep implementation of the arista.eos-vxlan role:

TASK [arista.eos-vxlan : Arista EOS Vxlan vtep resources (Ansible >= 2.2)] *****
ok: [DEV-ARISTA-LMAL-MAC-SW-WAN-01] => (item={'vtep': ['10.16.30.2', '10.16.30.3'], 'vlan': 2624})
changed: [DEV-ARISTA-LMAL-05] => (item={'vtep': ['10.16.30.1', '10.16.30.2'], 'vlan': 2624})
changed: [DEV-ARISTA-LMAL-GEM-SW-WAN-01] => (item={'vtep': ['10.16.30.1', '10.16.30.3'], 'vlan': 2624})

You can see that on the DEV-ARISTA-LMAL-MAC-SW-WAN-01 nothing is changed => because it is the only switch with an already configured default vtep entry, here is the vxlan running-configuration before the playbook execution on this switch:

DEV-ARISTA-LMAL-01#show running-config interfaces vxlan 1
interface Vxlan1
   vxlan source-interface Loopback1
   vxlan udp-port 4789
   vxlan flood vtep 10.16.30.99

And after the playbook execution on this switch:

DEV-ARISTA-LMAL-01#show running-config interfaces vxlan 1
interface Vxlan1
   vxlan source-interface Loopback1
   vxlan udp-port 4789
   vxlan vlan 2624 vni 2624
   vxlan flood vtep 10.16.30.99

=> the vni implementation is OK but not the vtep specific one. I also have this parameter set :

eos_purge_vxlan: false

I've tested it on version 2.1.8 of this role, and here is the ansible version:

ansible 2.9.18
  config file = /etc/ansible/ansible.cfg
  configured module search path = ['/var/lib/awx/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
