I have an icon I got from your shop. However it is not exporting properly, it is just blank as if there is nothing in it. I’ve attached a DEMO.sketch file (you can go to the link if it’s more convenient: “https://lun-jp.icons8.com/d/n4TF0lZCukKY7xkyVnVjKw?page=oITF0lZCukKY7xkyVnVjKw&vp=352,236,802,478”), try exporting the centre figure to SVG format.
Other icons in my project are exported safely.
