Peoplesoft Payroll, Separate checks get benefit deductions applied to even with "None" option

Peoplesoft Payroll, Separate checks get benefit deductions applied to even with "None" option

We are trying to pay some employees two paychecks instead of one, and we want deductions applied to the regular paycheck and no deductions applied to the second check (sep_chk_nbr  = 1). The second paycheck is through a row added on additional pay data. We have both checks in the same payroll. Also the employees that we have trouble with are employees of the DED_ARREARS table.
On the separate check, even though the  Benefits Deductions Taken and General Deductions Taken are set to "None", benefits are deducted from the check.
