Deductions & Expenses Report has incorrect entries

Hello,

I ran a Deductions & Expenses report for December 2018 this morning in order to advise my client of their payment amount for the January 15th remittance and discovered that that report did not pick up the adjustments made to one of the employee's pay cheques. I was comparing the yearly totals with the payroll payables GLs as well as the Employee Details report and our current CRA account balance to make sure everything was correct and thankfully found this discrepancy before advising my client of the payment amount; I always use that report-it always matches the GLs and the Employee Detail report. I have certainly made adjustments to pay cheques in the past and it has never created a problem before...what happened??
