My macvlan network has disappeared

I am using portainer-ce 2.9.0 version with the agent in docker swarm (LINUX Debian 10). I created a macvlan config file and then created my macvlan network from that config file. I added a few containers and no problems. My containers were using the LAN as I expected. I added another container manually but I cannot see my newly created network in the list of available networks to join.

Any ideas what the problem could be?

I have to bump this because I still cannot find the answer?
