So you have a few things going on.
You have another device in the home with Zwave that is possibly or probably interfering with Hubitat.
You have a Zwave, and not a Zwave Plus device. These do not send their state to the hub reliably, if at all. The Zwave poll app (built-in app) can mitigate this, however overuse of this app can significantly affect hub processing load if overused. You might be OK with 3 devices though.
Your mesh is very bad with only 3 devices. You probably have not even done a Zwave repair since adding these devices. See below for how to build out the mesh:
