Negative amounts putting my STP/Payroll Activity Summary Out

Hi, did anyone come back to you about this?  I have the same issue but mine relates to a final pay processed at the start of July where I have a negative amount to gross wages to adjust for annual leave taken in final week of work that was previously paid as gross wages in June, so my verification report doesn't match my payroll reports, even though the pay processed was accepted through STP.  The other odd thing, if you go into the individual's summary, the amount is showing there as a negative, just not in the verification report..
