I add another couple of Devices with Direct Rule , both devices are Member visible in site and receiving other deployments fine. --- check if the devices are appearing in the collection first.
Why if i go to monitoring - Deployments- and look for that deployment, they never appear - They might not have received the deployment, you need to check the client agent status, check if its active and get in to control panel > configuration manager client > actions tab and check if all the cycles are present.
