Hi
Is the issue about the one pay that hasn't been able to be matched?
You said that the bank feed had been automatched but not to the payroll cheque, Can you go into the payment that it has matched with and see what it is?
If it is not the correct match can you unmatch and put it back into bank feeds to properly match it with the payroll transaction
Investigate the automatched transaction to see if it a legitimate entry and match it to the correct bank feed transaction or delete it if it is incorrect or a duplication
Hope that helps
Lisa
