Description

Description

When creating and then removing an overlay network with swarm in the latest version, it seems to be only partly removed, as it cannot be recreated but it also cannot be deleted anymore.

Reproduce
# Create network - works as intended
docker network create --driver overlay --attachable wwcom_portal_prod

# Remove network - seems to work at first
docker network rm wwcom_portal_prod

# Trying to recreate the network again
docker network create --driver overlay --attachable wwcom_portal_prod

# Error response from daemon: network with name wwcom_portal_prod already exists

# Trying to remove the network again
docker network rm wwcom_portal_prod

# Error response from daemon: network ij8rdxwtn6kfc843egltdult1 not found
Expected behavior

docker network rm should fully remove the network so it can be recreated again. Currently the only way to solve this issue for me is to completely restart docker.

Research direction

Reproduce the issue with the Docker CLI commands docker network create and docker network rm for an attachable overlay network on a single-node swarm. Trace the CLI entry points for network creation and removal, then verify that removing the network releases its name and allows immediate recreation without restarting the daemon.
