Date does not fit the field

Date does not fit the field

Hi There.  I am having fun learning zoho sign API.

Today I noticed the "Signed Date" field does not fit, or alternatively the font is to large for the auto field space.

See screenshot below.

The signed date field is created by putting {{Signdate}} on the PDF prior to uploading to Zoho Sign.

Is there a way via the API that I can either make the field wider, or the font smaller so the date will fit properly?
