The issue here is not the plugin.
double check the code you have used to build the section.
You have the two-column div, then a paragraph, then two divs (left/right) that are floated, followed by two more paragraphs.
Set the paragraphs width to 100%, this will fix the your message section.
Remove the width of 95% on #two-column #right input[type=”text”].
For the paragraph holding the phone input add padding: 0 0 0 5%;
For the paragraph holding the email input add padding: 0 5% 0 0;
