Variable- Negotiation number not showing in Contract terms at Purchase Order

Summary:

I have created Clause and inserted Variable (Negotiation Number) in that. Then Created term template by using that clause. After that I have created a RFQ and attached that term template under "Contract Terms" train stop. In Contract Terms after refreshing system is generating the negotiation number in place of Variable inserted in clause. I have published the negotiation after that and awarded to Supplier. Created Purchasing document from RFQ; however, in PO under contract terms the Variable- negotiation number is blank. Need to add the Negotiation number manually.
