version 3.2.6.0 breaks woocommerce cart

Since this update;

• a customer adds a product to the cart with a value of (for example $100).
• the product is added to the cart.
• 1st problem; if the customer wants to delete his product by clicking on the cart page, the product is no longer deleted. He must delete it by clicking on the small cart that appears in the menu.
• 2nd problem; when the customer has deleted his product from the small cart that appears in the menu, theoretically, there is no more product in the cart. Also, the customer adds a product (for example $50) to his cart. When he clicks on the small cart that appears in the menu, the cart displays a price that does not correspond to $50. It displays $25 (for example). And he still cannot delete his product from the “cart” page. I specify that the previous version works perfectly. All previous versions have been working perfectly for about 6 years.
  
  Should I wait for a new version or is there a solution?
  
  I specify that I am under an “OCEAN” theme + woocommerce. I also specify that I worked without a cache plugin. I also regenerated the tables and css files. I also disabled all secondary plugins. The problem is still present.
  Thank you in advance for your answer.
