Reversed payrun shows zero in STP instead of a negative number

Hi, due to a network issue, I mistakenly recorded an employee's wage twice. 

When I noticed the error, I reversed one of the entries. However, in the STP Reporting Centre, the reversed entry shows zero instead of a negative number.

As a result, the total wage number reported to the ATO does not match the records in MYOB.

What should I do? Thanks!
