Unable to validate B2B invoices with a miscellaneous line type

Hello,

We are using OBN to get invoices from Staples. This invoices are matched to a PO, and they have miscellaneous charges that are prorated across al lines.

This is how the Lines are populated through a FBDI file

If I try to validate the invoice through the Validate Payables Invoices job, I get a Distribution Variance Hold because the Miscellanous line distribution account does not get populated based on the line 1, however If I validate the invoice from whithin through the Actions> Validate menu, the invoice gets validated.

As we have over 200 invoices per day, it is not feasible to enter each one and validate the invoices. Does anyone found this issue? Are there any setups that I could check? I made my research but couldn't find much on this, any help is appreciated.
