PO Date Change Ack wont pull stock items

After our last update to 6.00.529 we have an issue with our PO Date
Change acknowledgement report not printing items from "stock". It
will however print reoports for item not from stock.

The form was creted in Report Builder. I think it is a table and/or
linking issue but I cant seem to figure out how to correct this issue.
I dont have any experience in table/linking as of yet.
