The Plug-In Issues

Hi,

I have three issues.
1. When the plug-in is activated, the products do not auto-add to the cart on each product page. I have to refresh the page one time.
2. When it has the pop-up to add the product from the sidebar and I choose the variation and click add to card, the product that I choose does not go to the cart. Although I refresh a page, it still does not show a product.
3. I have an issue when I enable the Checkout on Sidebar Cart which I attached to the picture.

Thank you.
