I am creating a flow that has uses a FastLookup to create an sObject Collection, and then loops through that collection, updating an sObj variable- with the goal of creating records. Currently, rather than creating a record for each loop iteration, I have a screen displaying the values I intend to write to the record- so I can verify it's going to work properly.Three times now I have used an id field in the display text, and when I save as a new version and go back into the flow to do more work, the field has changed from {!vareachtemplatetodiscount.cnp_paas_evt__category__c} to {!vareachtemplatetodiscount.cnp_paas_evt__category__r} , and throws an error the next time I save a new version.I change it back to __c, but there's no telling if it will happen again the next version or two.What could be causing that?
