Overtime and accruing leave

I have an employee on an annual salary who works overtime every month. I balance out his pay (actual vs. award) every quarter and pay him the difference. However, when this is entered into the payroll info, it then adds in extra hours (which means more overtime) and extra accrued leave. Can anyone tell me how I stop this from happening please?
