Request e-Signature: Contract showing email glitch

The following leads to the glitch.  The document is emailed and signed by the recipient, then I receive an email prompting me to sign as well. It is here where I see the recipients email address doubling and offset. 

I now get a duplicate email when I send the document to the recipient and wondering if this is why the email is coming through twice. Does anyone know how to prevent me from getting a copy of the document when it is sent out but still enable me to get it after it is signed so I can sign it as well?

May I have your assistance with this two problems please?
