Autoinvoice Issue

 I have a problem importing invoices from OM.

The revenue account is set to come from the Transaction for all segments except one which comes from the standard lines.

When I create the invoice manually it picks up the segment from the standard line (item) without issue.

When I import the same transaction type with autoinvoice, I get a failure to complete the revenue account and the segment that is missing is the one that comes from the standard line.

The same item is used on a manual invoice and on the imported invoice, so autoaccounting should be picking up thje same valid account.
