Docusign eSignatue will auto populate to other fields, if you give the fields the same data label. This is a feature that allows the recipient to only enter the data once if it needs to be used in multiple fields throughout the document or even across documents inside the same envelope, depending on the configuration. If you don’t want to populate the same values across fields, simply give the fields different data labels.
