The nodes with the Discover button are not linked to a device on the hub, you should try to remove them if you can. It may or may not help.

Using the hub's built-in ghost removal tools
Below is a detailed summary from @jtp10181 of best way to use the hubs built-in ghost removal tools. Try these tools first before trying Ghost removal with a UZB stick:

• Click Refresh on the device ONCE, wait for the page to refresh. The Remove button should then appear. Click Remove ONCE. Again, wait. May want to have logs open while doing this as well.
• Sometimes it takes multiple tries of the Refresh button to get the Remove button to appear. Try to be patient and NOT click Refresh furiously. If you start getting "Zwave busy" error messages in your logs, power down and reboot again.
• It is common for it to take multiple tries at the Refresh/Remove buttons to remove a ghost, give it at least five or six attempts before assuming it's not going to work. Shutting down/restarting between successful removals can also help.
