Custom Data Elements not populating into SOV until first payment application is approved.

On a newly built Payment Application BP, we have used two custom data elements to record Qty(custom data element,Decimal Amount) & Rate(custom data element,Currency Amount)

The fields are included into the Base Commit>Options>Auto-populate on Payment Application,and they populate into the payment application as desired.But they don't reflect in the SOV sheet until, there is a claim against the line item on the payment application.Is there a way to surface values on the SOV for information that are populated from from the Base commit like the Qty & rate.The Scheduled value however populated values on the SOV as soon as the base commit record is approved, we are using scheduled_value here on the SOV.
