Hi,
Thank you for reaching out here in the DocuSign Community.
By default, our eSignature application should allow your signer to enter their title during the signing session or auto-populate it (if there is a title set for the user) as long as you are using the Title field.
If your recipient is unable to complete the Title field, I would suggest using a text box as a quick workaround instead.
And in the case that you wouldn't like to use a text box instead of the Title field, please refer your signer to us so we can take a closer look at the envelope and error that is being received to appropriately address the issue on your behalf.

Please don't hesitate in letting me know if I can facilitate anything else in the meantime and I will address your request as soon as possible.
Best regards,
