Responsive Social Icon Nav Not Displaying Correctly

(sorry for all of the questions!)

When my phone (android) displays my website, the responsive social icons at the top do not display correctly. They shrink down to what I assume would be a pop-over navigation (similar to the main nav), however, when I try to tap/click/select them on my phone or computer (when the browser is very narrow), nothing happens.

Here is my site: https://www.inthelittle.com/

Is this a result of settings I need to change within the theme options, or is this an error of some sort?

Thanks for looking into this!
