Report Manager is a historical database. Meaning, it will store historical data for devices.
If a device is destroyed we will update the device as destroyed in the reporting database, not remove the entry. This enables users to report on past data for the device, should they choose to.

The fix for this in adhoc views/reports is to add a filter for destroy_time being blank.
In the database, a NULL value will let us know its an active device. Any sort of date value indicates the device was destroyed.
