How to remove ghost devices?

Hi all, I would like to ask if there are any possibilities to remove ghost devices that stuck on hub C-7. I got those ghost devices when tried (2 times) of pairing smoke/co2 detector device with S2, first two failed and was not able to detect correctly mentioned device. I tried to shutdown hub, reboot and also remove but no one removed them from the list of zwave devices. Thanks in Advance [ScreenShot_]
