STP reporting issue

FY22-23 EOFY payroll reconciliation has been done in July 2023, all three reports were matched well, the MYOB payroll activity summary report, MYOB payroll register summary report and STP YTD verfication report. However, when I was checking the list of payroll transactions under 'STP reports' in Payroll Reporting Centre just now, gross payment for one payrun report during that period turned to nil while PAYG and super are correct all of sudden. Nothing has changed and payroll for this payrun had been processed as normal for sure (Otherwise the YTD verficiation would not be matched with MYOB payroll reports, isnt??) Can anyone advise what is going on, and how to fix it please?

PS: On this employee's MyGov account, the Gross wages (tax ready) for FY22-23 is correct, which is the same as MYOB figure. I believe the correct Gross payment for this "Nil pay run" should have been reported to ATO in Jan 2023??

It will be greatly appreciated if anyone can help. Thank you
