Issue is occurring on a handful of our job requisitions, so appears to be position/requisition specific? As other mass job offers we have created worked without issue. Confirmed the Position Name matches the Position Name on the Job Requisition and do not see any issues with the Position or Job Requisitions (Job Offer and Requisition are after the Position creation date and no further changes have been made.)
