After running Payables Open Interface Import, invoices are posted to wrong account on the distributi

We are running the Payables Open Interface Import using the source as EDI Gateway. We have invoices for two stores, 232 and 376. When we run the EDI Inbound Datafile Import Process, I have reviewed the AP_INVOICE_INTERFACE and AP_INVOICE_LINES_INTERFACE tables. I have found documentation that the accounting gets done by the data in either the dist_code_combination_id, the dist_code_contcatenated or distribtuion_set fields. I validated all the invoices for these two stores from the AP_INVOICE_INTERFACE table that one of the three were populated. And the distribution_set_name field was. It contained either 232 and 376.
