config_runbackfilljob fails to run using datafactory studio to run the job

🐛 Problem

running pipeline config_runbackfilljob in data factory studio fails to run. Set the scope config in settings.json however once you try run the job you get a myriad of errors

One was export time cannot exceed 84 months
One was startdate and enddate must be in the same month and another was
Either both startDate and endDate needs to be present or both should not be present."

Date format used for the above tests was DD/MM/YYYY

On Second round of testing using a single month with date format MM/DD/YYYY it worked for one month only

Using the same MM/DD/YYYY and spanning multiple months it fails, this was a backfill pipeline and has a variable start and end date, you would assume you could put in start date 13 months ago and end date current date to get 13 months of backfill but that is not working.

Start by reproducing config_runbackfilljob from Azure Data Factory Studio using the settings.json scope configuration and the reported DD/MM/YYYY and MM/DD/YYYY date ranges. Compare single-month and multi-month backfills, then define done as allowing a valid multi-month startDate and endDate without the conflicting validation errors.
