Can you pls check if you have the widget area named “Header Area” appearing in the Appearance->Widgets page. There you can drag a text widget with flag related HTML inserted. This option is available only the latest version of the theme and hence you may need to upgrade to 2.6 version to see this. Alternatively, you can modify the theme file header.php at line number 68 and enter your custom HTML there with the flag icons if you have the old version loaded. Then, you need to have below custom css to hide the cart icon and style the new flag section appropriately –
/*Assuming you are wrapping the flags section with flags-section class */
#header .flags-section {
padding: 0;
position: absolute;
right: 20px;
top: 30px;
}
.woocommerce-site .cart-contents {
display: none;
}
