Hassio losing zwave entities

Any ideas on why hassio randomly drops entities from z wave devices? Tried repairing the sensor, all that got me was a mess of reconfiguring and a now completely useless sensor. While the other entities did start working for a short time the sensor says the door is open while it is very clearly closed. Then after a reboot I’m right back to where I started with nothing working. Also noticed the name changed from aeotec to aeon after repairing.

Also why is there no way to clean up/remove old and unused devices?

I have the same issue with fibaro devices - both battery powered and wired. Entities disappear sometimes reappear. The devices themselves seem to work fine - the remaining entities work .
My fibaro motion sensor also has only the “sensor” entity right now (like your window sensor) even if it worked fine directly after pairing.

I ended up having to exclude/include it several times and reboot between pairings. That got what ever bug it had up its butt out… for now.
