Acq items from OPAC View View/Place Orders not linked to PO provider

Evergreen version: master

When using Actions for this record/View/Place Orders from the OPAC View, I clicked on the button to send a title to an existing purchase order. I entered the PO ID# and my title was added as a new lineitem with a status of “pending-order.” However, after adding a price, the Activatable message said “No: The lineitem has no provider (ACQ_LINEITEM_NO_PROVIDER)”. The line did not get associated with the provider I used when I set up the Purchase Order.

In our system, an example of this can be found on PO ID 8463
Lineitem ID 167841
Title: Beadwork. Author: Ciotti, Donatella ISBN 1581803273 2002 North Light Books.
Record ID# 1656788

These are all the error messages that displayed on the Java console right after performing the above described action. I don't know which, if any, may be relevant.
