Postgres RDS Blue Green Deployment Setup Not Working

I'm trying to setup a blue/green deployment of my Postgres 14.10 database.

On the database, I can see the following settings.

However when I try to create the blue green deployment I just get the following error after creating the deployment.

Creation of blue/green deployment failed due to incompatible parameter(s): [max_logical_replication_workers] .See https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/blue-green-deployments-creating.html#blue-green-deployments-creating-preparing-postgres to help resolve the issues, then delete and recreate the blue/green deployment.

Is the UI telling me the wrong thing and it's something else that's broken w/ the setup?
