Hey @qdmt,
this is unrelated to this topic, but I stumbled upon a earlier (now closed) thread from you. Current Method for Resetting Variables - #4 by denisfi
Maybe you have already solved the issue. If not, this might be a nice new pattern to use. When you do a flow variable connection on the invisible edges every node has, this impacts the execution.
As shown in the second screenshot: If I reset an earlier (upstream) node, every other connected node is reset.
This should solve it. I think that, because in a screenshot from the old thread the flow connection to the Create Date&Time Range node was missing.
