I have a problem with a Witty Pi4 setup (Pi Zero W, configured to run 3min every 15min) , which doesn't shut down sometimes.
From the log i identified the scheduler to be the problem, as it is not executed in such cases.
Any ideas?

You need to look into the wittyPi.log file. The log you provided is from the schedule.log file, which only tells what happened/not happened, but does not give any hint about why.
