Social Media Icons are not updating

Hi support team, I have an issue on my theme, I try to update social media icon links but nothing is showing up, but when I visit site using admin signed in, it’s working fine. only one link is showing up which even didn’t have the link I inserted. I’m also attaching the snapshot so you can see the issue by your self.

Here is the site link, you can check it by yourself: http://www.fcstriker.com/
