How to Roll Back and Delete Payroll Flows

Summary:

We are trying to delete a Payroll Flow that has only been run once, two years ago. We have run the Roll Back process for the one instance that it was run, which has completed, but when we try and delete the flow, we still get the following error message, "The report format mapping can't be deleted because it's referenced by payroll actions. (PAY-1635388)" Does anyone know a step we are missing or something else we need to do to complete the deletion? Any help is greatly appreciated.
