Action 1 is a great patch management system. However one thing you should not do is add the action 1 client when imaging, the client should always be added on after or you will need to run a script to clear a registry entry.
The issue looks like this
The client that was imaged shows up but then when the action 1 client is imaged and deployed it doesn't change a registry entry so when you have systems with the action 1 client imaged and deployed the clients over write each other in the action 1 web interface.
Uninstalling and reinstalling the action 1 client will not fix the issue however clearing the registry value should, and should not require re-installing the client.
On the affected system(s) check the registry
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Action1The 'agent guid' should be unique, if not stop the service and clear the registry value; then restart the service.
You can also get the information for this fix form Action1

2) Open Start > Services > Stop 'Action1 Agent' service
3) Open Start > Regedit > Clear 'agent.guid' value
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Action1
