Question: E-signature

When I send out pdf for requesting e-signatures,

I received a complaint that when the receipient receives the pdf to sign, it autopopulates their name. (In this case, it says Michael)

Then they have to do the extra work to change their signatue style.

How can I send the file for e-sign, where the recipient receives a balnk "Type your signature above" column. Is it related to sender or recipient's setting?
