Single Pay Voucher build created by XML batch appear to be going through eSettlements workflow appro

We are going live on 9.2 and are in integration testing.  Finance is telling us that the single pay vouchers from their patient accounting system that are being uploaded as xml to batch voucher build are going through eSettlement workflow instead of normal voucher workflow.  I believe this must be a setting but they are telling me it is not.  Has anyone else encountered this?  Any help would be appreciated.
