Buy X get Y Problem

Hi,
I’ve got a problem with the Buy X, Get Y type. I want to discount users for a specific category if they already added a product from another category to their cart.
But the product price on the category/product page is showing incorrectly – https://prnt.sc/BydcSzZBWl_l
On the cart page, the product price is correct. My settings – https://prnt.sc/T7IwYOCG_WGT
I need to replace the price because I’ve another rule that applies discounts for all products from specific categories.

As I understand problem is in function – change_product_price_html, you don’t have the logic to check are all rules can be applied. Can you fix it?
