Odd Fontello issue

I had downloaded one icon from Fontello to use in addition to the standard, and it worked fine.

Today, I went back and downloaded the first one plus 5 others, but they do not show up like they do on Fontello once they are loaded onto the site. I have deleted, downloaded again, and still the wrong image. On Fontello, when I look at Customize Codes, they look fine in the center, but the image above is what actually shows up when loaded into site. I have attached images for review.

Any ideas?
