Batch User Matched and Paid Voucher

We have a vendor setup via EDI that pulls in invoices and creates a voucher.

Our batch user, EDE_BATCH, that runs every night to pull in the invoice and runs the voucher build, somehow matched and posted the voucher on it's own.  EDI invoices always need manual intervention for matching and posting, but for some reason the invoices from 11/14 did not. 

We had invoices from 11/12 come in correctly without this happening, but 11/14 EDE_BATCH matched and posted.

Any ideas where I could start looking why this happened?
