Why the social icons aren't working in my Wordpress website?

I am writing this post because I can't solve a little issue that it's driving me crazy. I've developed a website using wordpress, and I have some social icons at the bottom of the menu (you have to click in the burger menu icon, the menu will appear and below the links, are the social icons):

I've wrote my social links in the template plugin options, and the four of them are well written, but it looks like the icons are not even receiving the links I've written.

I would like to make these social icons work. How can I fix the links? Please, help! Thank you very much.
