I’ve ran into some issues with Advanced product fields option / variant pricing in cart / checkout:
When I select an additional flat price option in my product and add it to cart the variant price shows up in cart right below the main product as <option name (+price), however it alters the price of my product inside the cart item e.g. if my product has the price of 100$ and the option is 50$ it shows the price of my base product as 150$. The same thing happens in order subtotal / summary area, the price of the product is displayed as 150$ and it doesn’t show any text/info that a custom option/variant was selected. I want to make it so that cart summary shows base product price and the variant price separately in subtotal, then the summarized price in order total.
Another issue I ran into while setting up the above option is that if your custom option doesn’t have a label but it does have options theres a “:” sign displayed in cart/checkout as if there was a label.
