How to Configure Account to not show email address of person sending

[dfaberwespath]

I know this is possible but the Adobe User Guides are lacking in terms of how to do this.

Simply put: When I send out an agreement for signature, my name as the sender is showing on the email even though on the Email Settings setup page, the 'Hide the sender name and sender email from the "Signature Requested" email" parameter is checked.

The form I am selected is not owned by me (as I assigned it to a default company name user) so can someone convey what I am missing here.
