Hey IanKSG,
Welcome to the MYOB Community Forum!
I see that you're having issues with the pay period and date of payment showing on the STP reporting window. To ensure the correct pay period is showing on the STP (Single Touch Payroll) reporting, the pay period of the actual pay runs should be reflected. Based on the screenshot you've attached, it appears that the transactions are update events, which typically show zero figures. To verify if it's an actual pay run or just an update event, check the amounts of each transaction. Actual pay runs will have figures, while update events will show zero figures. This should help you find the correct transactions.
Best regards,
Doreen
