How are you checking those systems?
What is in the console is correct for the version.
Most likely you are trying to check via registry entry. Right now when an agent updates via the manager it is not updating the registry entry. If you are using the agent installers to update then it should overwrite the registry entry to put it at whatever the latest version is at that time.
Updating the registry entry when the agent updates via the manager is something we would like to do at some point in the future.
