Sort out the shopping cart

Moved hosting. The php version was 5.6, on the new hosting 7.4-8 (tried and 5.6 return). As a result, a bug was found when adding https://luxurytextile.ru/ to the cart, the total number of products shows the correct one, and only 1 product is displayed in the cart itself. Screenshots attached. I also attach a foreech of goods from the basket and the function of the shopping cart module.
