Developers will have to fix the issue with the icons via the child theme. Issue with the color of the wishlist disappears once you press the publish button to apply changes not just of the multiple headers but general Publish button.
Developers need more time to fix the cart issue of the vertical header. I’ll inform you about the results.
I checked the mini-cart and mini-wishlist and menu and don’t see the problem https://gyazo.com/1b154debcd4b64e20b24d6f4dbeffc19
Could you, please, provide us with link to the page with the revolution slider to take a closer look at that? I think you have some negative margin for the revolution slider section and that causes issue.
