Stop NodeRed from sending / processing when re-deployed


I have a few Smart Home one time events using NodeRed, f.e. a sleep timer, light toggle and so on.
Problem is, as soon as I re-deploy after changing some stuff, all messages which have been incoming are re-processed, and all outgoing are re-sended: light toggles, sleep and wake up timer start and so on.
I always thought, a QoS 2 message for example, is meant to only ONCE being processed?

Is there any way to change this behaviour, i.e. just save new notes without re-processing and re-sending?

Is the retain flag on for those devices ?
Note that you can change the deploy setting to modified nodes/flows only.
