Entitlement Balance differs to Employee Payslip

I have had an employee leave and I paid out their Annual Leave accrual from the Entitlement Balance Report.

They have now come back to me and queried their entitlement payout as the hours paid out differs from what was appearing on their payslip.

I have reprinted the Entitlement Balance (Detail) report and the Payroll Advice for the whole of the financial year and they differ. I have a copy of the Payroll Advices from when I actually processed the pays and they are the same as the Entitlement Balance report.  I haven't made any adjustments to this employees accruals. I have attached reports for reference.

I don't know what is going on and how to fix it.
