newsletter boxes

Hi team,

I have a paid version.
please have a look here: https://moreyouthfulskin.com/cs/domu/
the upper line of the box is doubled – how can I remove the second line, so there is one box only?
Which code should I use so that the titles in the newsletter boxes on my site disappear when someone types in their data: name, surname, email?
Thank you in advance,

Milada
