Font stuck in italic

Every since my last Twenty Eleven theme update all of the font on my blog https://parentingmultiples.net displays as italic. When writing the font displays as Helvetica Neue. I checked under editor and the Global options for font as as they should be:
/* =Global
———————————————– */

body, input, textarea {
color: #373737;
font: 15px “Helvetica Neue”, Helvetica, Arial, sans-serif;
font-weight: 300;
line-height: 1.625;
How can I change this so all my font does not display as italic. Also, when writing I am able to distinguish between italic and normal font, but when published there is no difference in font style.
Thanks!
