How can I remove unintended signers and signature fields from an agreement already in progress?

I sent a Request e-signatures agreement to multiple recipients using my personal Adobe Acrobat account. I accidentally included two of my own email addresses as signers when I intended only to be copied on the request. Acrobat consequently added two signature fields for those addresses that were never intended to be part of the document.

Several legitimate recipients have already signed, so I would like to avoid canceling and resending the agreement.

I do not have Modify Agreement or Remove Recipient available under Manage. I can see Replace Recipient, but my understanding is that this would simply transfer the unwanted signature fields to another recipient rather than remove them.

Is there any way to:

1. Remove the two unintended recipients and their associated signature fields from the active agreement;
2. Preserve the signatures already collected; and
3. Allow the remaining legitimate recipients to continue signing?

If this is not possible with a personal Acrobat account, would upgrading to Acrobat Sign Solutions allow me to modify this existing agreement, or would that capability apply only to new agreements?

Thank you for any guidance.
