Are you sure the Zooz MultiRelay-Relay 2 was off before 20:42? If it had been on, the switch on would not represent a change, so it wouldn't trigger. What turned it off before 21:03? If the relay turns off while the Required Expression is false, that will not be reflected in the internal state kept for the relay, as none of the event subscriptions are in place then. You may want to do this a different way than a Required Expression.
It could be debated that RM should be re-establishing the state for changed triggers upon the Required Expression becoming true; it may not do that now. I believe this issue is addressed in the next release. That most likely means that it doesn't do that properly in 2.3.5. Edit: I just confirmed this: RM fails to re-establish prior state while Required Expression becomes true in 2.3.5, but does do this in upcoming 2.3.6 release.
