I’ll add that you could use MIN or MAX group functions if you are looking for all member shutters one way.
These messages come from autoupdate, having a pre-emptive guess at the outcome of a command. Where you’re expecting a timely update from a real device, it’s usually sensible to set autoupdate false for that Item.
That’s something worth looking into, on the zwave side (about which I know nothing but has already been discussed).
But - I don’t see the other shutters reporting either, in the events.log snip you’ve shown us. Maybe they do later, but the events shown look to me like they are results of autoupdate predictions.
