Just to illustrate the problem:

If you're using zwavejs2mqtt you should not have the official Z-Wave JS add-on installed. Remove the latter add-on and the discovery notification should disappear. You may first need to reconfigure the set up Z-Wave JS integration to not be configured to use the official add-on, if that was selected when you set up the integration. You can go through the config flow again and uncheck the relevant check box.
