The rest of your issues are very strange (and, as Bruce says, require debug logs for anyone to make much sense of).
This particular behavior, however, has been seen by several people trying include certain battery devices in OH3 (here and here to name a few examples). Again, the cause of this is still not known so debug logs are doubly important to help us provide the dev with more information on what’s going on.
As a work around, depending on your setup, you may be able to use a different software to do the inclusion. I found that my three battery devices that failed repeatedly to be included by OH3 were all included completely on the first try with Open Zwave Control Panel and were then easily and fully discovered by OH3 and work 100% (Other software such as OZWCP will also let you erase any zombie nodes you may now have if you see performance issues as Bruce stated).
