To resolve this issue and ensure the inventory reflects the correct NSX version, restore the NSX adapter to a healthy collection state:
Log in to the VCF Operations UI as an admin user (https://<VCF_OPS_FQDN_IP>/ui)
In the left navigation pane, go to Administration > Integrations.
Expand the configured NSX adapter instance and review its current status.
If the adapter is in a 'Warning' state, select it and edit the configuration.
Click 'Validate Connection' and confirm the connection test is successful.
Save the configuration and verify that the adapter transitions to a green Collecting state after the next collection cycle (~5 minutes).
Once a successful collection cycle completes, the inventory will automatically refresh and display the updated NSX version.
