Only 3 social icons at top of page?

Hi all,

I just installed this theme today, and think it’s very nice. I am trying to add some social media links to the top, and so far have four entries. Linkedin, Facebook, Twitter, and then I tried Twitch.

Well the icons show up for the first three, but the fourth spot (you can see it divided like there “should” be an icon there), but no icon shows up. At first I thought it might be that Font Awesome wasn’t working, and didn’t like Twitch. But I kept the link to Twitch, and swapped out the Navigation label with google, google plus, basically some more mainstream icons. No icon will show, but the menu is clearly divided into four sections.

Any idea what I could be doing wrong? I really like this theme, and works great otherwise. I tried searching, but haven’t found an answer.

Sorry, I should add that if you click the space where there’s no icon, the link works, and opens the page as it should. I also have adblock turned off.

Thank you!
