Try doing a backup and restore to clean the database up, probably wont help with zwave but worth trying.
Also, there is more to look at on the zwave details than just ghost devices. I am not overly concerned with ghosts unless there is a massive number. There is other stats on there which populate over time that tells me a lot, so it is best to see it after 12-24hr+ so some of the stats can accumulate.
I still don't even know what hub firmware you have, you did not answer any of the questions asked in my pinned post.
What version is the zwave firmware as well? (Do you have an update firmware button on the zwave details page)? Z-Wave Firmware Update - where is it?
