Just to clarify, rebooting won't help w/your Z-Wave radio, you have to shut down, pull power, wait 30s, and then plug the hub back in again. That process will "clear" the Z-Wave radio. Doesn't remove any devices or data, just refreshes the radio.
The current platform version is 2.3.8.125, you should update to that version. Settings>Check for update, and update to the current version.
You have a bunch of ghosts, and will need to work on them. You may be able to remove some of them using the hub's built-in ghost removal tools, but in the end you might have to get a Z-Wave USB stick (aka UZB stick) and remove the ghosts using a more complex process, unfortunately.
Good idea to disable your polling app for now, as that puts extra load on your mesh.
Your devices aren't being harmed, they are just not communicating effectively w/the hub, and vice-versa. So no device damage, you don't need to worry about that.
I would update to 2.3.8.125, do the shut-down/pull power/wait 30s/plug back in and re-check what your Z-Wave Details page looks like to see if any of the devices look normal again. That might happen, but no guarantees.
Then to start working on removing the ghosts you need to do as I said above and look at the ghost removal topic...
Assuming you're up to date, see this post on removing ghosts . Start in section 3 which covers using the hub's built-in ghost removal tools.
