Automation Filter / NAT Port Forward

[mattbridges]

Does anyone know if you need to do something else in opnsense to be able to toggle firewall rules in the automation filter as I can open ports using the NAT port forward but when I put (what I think) is a carbon copy in the automation filter, the same rule doesnt seem to work?
Screenshots of the NAT Port Forward rule and the Automation Filter to show what I'm trying to achieve.
