Unfortunately a question like this is better handled if you contact Sage 300 ERP support. You will be requested to provide examples and more details. It many cases this is setup related or a timing issue. The employee with the problem may be using a different earning\deduction code and taxes vs the other employee that has no issue with W2 reporting. It may also be that the employee didn't have the right setup earlier in the year and was only corrected later after a few payroll runs.
