There is a glitch where if certain devices are removed from the dashboard, they will still show up in the Anti-Theft module.
For example: If Bitdefender Mobile Security is installed on an Android device, and removed from the device at a later time, that device still will show up in both the dashboard and the Anti-Theft module. The device can be manually removed from the dashboard. That device will still be displayed in the Anti-theft module though, and there is no way to remove it.
