Check the column cell name in your Excel template (Insert > Name > Define) and compare it with the Payroll Report Code window in NV2 for that cell definition with the employee in question. Is there multiple account suffixes for that employee that match the cell specified in the NV2 Payroll Report Code table that Excel is reporting on?

I would need to see the:

Payroll Report Code Window
Employee Paayroll Record (Account Setup)
The excel template and your current output.
