The issue may stem from reprocessing the super payments before Kai-Ti’s updated details were finalized with the super fund. Since you recorded and reprocessed the June/July payments on the same day the returned super was recorded, it’s possible that the old, incorrect details were still in place at that time. The August contribution might go through if the correct details were applied before that payment, but for past contributions, you may need to reprocess them again now that the correct details are confirmed. Checking with the super fund to ensure everything is updated before resubmitting would be wise.
