Deleted VMs continue to alarm as offline, months after removal

I have an alarm created to warm me of VMs being powered off which is working fine. A handful of deleted VMs are alarming that they are offline, months after removal. I have went searching in the Data Management to see if there was still references to these non-existent VMs but could not find anything. Is there anywhere else within vFoglight that could still be tracking these deleted VMs?
Thanks
