nxos_vlans result always returns "changed": true

[Raimond56]

I couldn't find any information on it elsewhere.

SUMMARY

When running cisco.nxos.nxos_vlans to create new vlan and then run the playbook again it always returns result as "changed" where it should return "OK" instead.

STEPS TO REPRODUCE

Create new vlan with playbook and run playbook twice

- name: Testing playbook for nexus
  hosts: n9k_lab
  gather_facts: false

  tasks:
    - name: Create new vlan and add vn-segment
      cisco.nxos.nxos_vlans:
        config:
          - vlan_id: 50
            mapped_vni: 5050

EXPECTED RESULTS

After running playbook second time and vlan already exists I expect result to be OK
PLAY RECAP **********************************************************************************************************************************************************************************************************************************
n9k_lab : ok=1 changed=0 unreachable=0 failed=0 skipped=0 rescued=0 ignored=0

ACTUAL RESULTS

When running playbook again when vlan is already in place, always getting changed. See below.
It seems that after and before are different the module automatically adds "mode":"ce" to after list

Is this bug? I think it should show OK if no new vlan was added.
