Removing a signer from Document Cloud eSign

When we originally sent the doc the admin wasn't sure which email was correct.  They put both emails in to be signed.  How do we remove one of the signers?

Unfortunately this was also set up to sign in order and the first email was incorrect so the second signer isn't even able to sign and can't replace the first signer since it's the same email as the second.  Or can we at least change the order on signers?  This way once one is signed we can upload the signed copy to correct the wrong email.

Is the only option cancel and start over or is there another way to correct this.
