Receipents Name added while Prepare document are not showing after sending document for Signature

Thruogh Agreement View Api I have prepared an agreement, at the same time in the receients list I am able to see the names of receipents along with the emails.

But when submit the agreement for signature, It is not showing me the receipents names and shows only email addresses of receipents.

In Api I have  added the name of receipents in NameInfo model in ParticipantSecurityOption in participantSetsInfo 

Please look the video of the same for the better understanding.
