Hi,

This issue have been fixed on new version of theme.

You can update to lastest version to solve it.

If you don't wanna update theme, you can help me find this code on file style.css

.select2-container{
            display: none;
        }

remove it and insert this code 

.ftc-search .select2-container{
            display: none;
        }
        .ftc-search-product .select2.select2-container{
            display: none;
        }

Let me know if you have any problem with our theme.

Don't forget rate our theme and follow us on themeforest to get information about update theme.

Thanks
