Regarding the ghosts in the your Z-Wave Details table...
You spoke about the ghosts at the bottom of your Z-Wave table, but you have three devices part way down your Z-Wave Details page that don't look good:
Are you saying that these three don't behave like ghosts - you can control these devices from their Device pages, and they function normally in automations, etc.? These appear to need action as well as the ones at the end of your table.
You have a Z-Wave controller added - not sure from what you said - have you tried using the PC Controller app w/the UZB stick to remove your ghosts? What happened when you tried? You followed the steps in the PDF download in this topic?
Regarding the three below...that seems clear, Remove button isn't working. Have you tried Refresh and then Remove on any of those devices?
Generally, removing ghosts on Z-WaveJS has been found to be pretty straightforward. Hopefully we can get you there...
