[Resolved] Woocommerce cart 404 error after installing WPML

Background of the issue:
1. I want to translate client's shop but after WPML installation there's additional cart, shop, order and terms of service pages that replace default pages. After deleting them and replacing hooks in WooCommerce settings for default ones (as your support suggested to me yesterday - screenshot), 404 page still displays in place of cart page. I've created a staging site to check it. Link to a page where the issue can be seen: hidden link

2. Also when I first try to create translation for cart page in English (before I deleted automatically generated pages by WPML) by clicking on + on Pages in WordPress panel, it was working but styles of translated page were different from original page in Polish (see screenshot 2A is correct and 2B is translated page). This is not acceptable.

Symptoms:
1. 404 page displays in place of the cart page after following support's suggestion to delete additional pages and replace hooks in WooCommerce settings.

2. After translating cart page, styles are not matching original page.

Questions:
1. Why is the 404 page displaying instead of the cart page after following the support's suggestion?
How can I correctly set up the cart page to avoid the 404 error?

2. Why styles are different on translated pages?
