Contract Source is Attached Document, but no Primary Contract has been upload

I did a contract amendment for an executed contract to create
a new contract. I received all the necessary signed documents from Docusign. I
went in to upload them to the new contract and the system won’t let me submit for final approval.
Every time I hit submit I get the below error message:

Contract Source is Attached Document, but no Primary Contract has been upload

   I have the contract terms attached in the attachment section
since we are using the contract terms from a previous version.

Please help me get this submitted so that the status is no
