Copy Control - Address Details from Quantity Contract to Purchase Order

Question

Dear Experts,
When I create a Purchase order w.r.t a Quantity Contract, in some cases the address details (such as street address, phone #, e-mail etc.) are copied from Quantity contract and in other cases they are copied from the vendor master. I compared the vendor masters and quantity contracts in both the scenarios and cannot figure why this is so.
The way I create a PO is to use the selection variant option in ME21N to pull in the Quantity contract and then 'Adopt' the details.
Is there a address copy control functionality somewhere at the vendor master level that governs this behavior?
Examples:
1) Vendor A has telephone [phone] on vendor master data and QC 5000001 has 999-999-9999 as telephone for the same vendor in the quantity contract. When I use this QC, 999-999-9999 copies over to PO and this is desired/correct
2) Vendor B has telephone [phone] on vendor master data and QC 5000002 has 999-999-9999 as telephone for the same vendor in the quantity contract. When I use this QC, 888-888-8888 copies over to PO and this is not desired/incorrect
Any insight would be helpful
Thank You
Siva

Hi Arminda,
The note refers to the Plant/shipment Delivery address and I am having trouble with the communication address (supplier address, email, fax, telephone etc.) of the vendor.
Any other inputs?
Thanks
