Payroll activity report - Gross earnings vs Taxable earnings

Hi there

I have just run our Payroll activity report for 01Apr to 30Apr25.

One of our employees shows a gross earnings of $9497.62 and a taxable earnings of $7507.14

When I check the 3 payslips covering this period and add up the gross pay figure and the taxable earnings figure, they come to a total of $9497.62

I cant work out where the $7507.14 figure has come from.

I have included a few screenshots:

The first is from our Payroll activity report and the next 3 are from the employees payslips over the pay period in question.

All of our other employees are showing the correct Gross earnings/Taxable earnings.

Payslip1

Payslip2

Payslip3

Any ideas on what the problem could be, please?

I need to be able to explain to my manager/auditor why the figures don't tally.

Thanks for your help.
