Incorrect pension contribution

Quickbooks has calculated the employer pension contribution but has calculated an incorrect amount. 

The Quickbooks calculation is shown as follows:

Employer Pension Calculations

£2,617.26            Gross Pensionable Pay

£520.00               Lower Earnings Threshold

£4,189.00            Upper Earnings Threshold

£2,097.26            Employer Pensionable Earnings

3.00%                  Employer Rate

£43.50                 Employer Pension Contribution

Clearly these calculations are correct apart from the final figure. 3% of £2,097.26 is £62.92. Why would Quickbooks get this calculation wrong? This is one of 59 employees and is the only one with an incorrect calculation.
