Constant Contact API Widget 2.4.1

Hi, it is me again! I have loaded the Constant Contact API Widget 2.4.1 and "designed" an email signup form to appear in the sidebar of all secondary pages. The form in the editor looks great, when it is in the sidebar the text the describes what the fields are "First Name," for example, is on two lines, I need the text to be on one line, is there any way to correct this. As always, all help is greatly appreciated! http://plantricious.com/about-us/
