I asked a similar question on github a few weeks ago. Question on SET - GET and Command poll. · Issue #1904 · openhab/org.openhab.binding.zwave (github.com) I don’t recall when I thought I started to see this or whether it was always this way.
If your logs look the same, you could try to disable the command poll settings (1500 → 0). The “report” could be off with slow acting devices (dimmers), but otherwise it might work (with less traffic).
