STEPS TO REPRODUCE

current config on device

vlan 308
  name demo_vlan
  vn-segment 10333

playbook:

- name:  Create VLANs on Fabric
  hosts: leafs
  gather_facts: no
  vars_files:
    - vars/vlans.yaml

  tasks:
    - name: create vlans
      cisco.nxos.nxos_vlans:
        config: "{{ vlans }}"
        state: overridden

vars/vlans.yaml

vlans:
 - { vlan_id: 308, name: "demo_vlan" , mapped_vni: 10308 }

EXPECTED RESULTS

new config on device:

vlan 308
  name demo_vlan
  vn-segment 10308

ACTUAL RESULTS

config unchanged

nxos_vlans module does not seem to issue a "no vn-segment" command when the mapped VNI needs to be changed.
NXOS CLI issues the error that vn-segment cannot be changed only AFTER one exits from VLAN config mode.
