Well thats odd because my headline looks nothing like that.
When I inspect the element it is literally: Helvetica,Arial,sans-serif with a font size of 1em.
I opened up a new Chrome Incognito window to clear cache and it still looks the same.
I even tested it in Internet Explorer and it still looks the same so I have absolutely no clue how youre seeing what youre seeing.
In addition, when I am scrolling through my list of available fonts, my Typekit font isn't there anywhere.
