Multiple Purchase Orders getting created for a single requisition

Summary:

We created a requisition having 3 lines with BPA reference and one line without BPA reference in it. Automatically Generate Orders flag is enabled in the BPA. Upon running the Generate Order process, 2 POs got created. One with the 3 items with BPA reference and the another PO with item without BPA reference.
Our client wants to see all 4 lines in a single Purchase Order. Is there a way to do that?
