I've added bello pro from typekit but it's not showing the correct font face. I've also added localhost to my typekit but only after finding it it did not work the first time without it.
Are you able to use other fonts from your kit on that page? If so what other fonts are you using? Can you use Bello Pro correctly on other pages with same kit and it's just this page? I created a simple kit with just Bello Pro and it worked correctly for me on a simple page so there might be some combination in either the kit settings or how it's used on the page that's causing this.
