How to Remove Default Signature Block and Email Address Added to Bottom of Document by Acrobat DC's Sign and Send Feature

I am using the Adobe Acrobat DC Sign and Send to have someone electronically initial a document.  I added the initial block next to the person's name, and it is the only block that appears when I preview the memo.  However, once I send the document, Adobe automatically adds a signature block with the recipients email address underneath it at the bottom of the page.  I cannot find a setting that will prevent this from happening.
