Cart & Checkout pages not displayed correctly for language version

I have 3 language version of a Woocommerce product, with English as the default language:
https://yourlondontutor.com/services/itinerary-planning/ – English
https://yourlondontutor.com/es/services/planificacion-del-itinerario/ – Spanish
https://yourlondontutor.com/pt/services/planejamento-de-itinerario/ – Portuguese

When I open a product in Spanish or Portuguese, the ‘add to cart’ and ‘view cart’ buttons are displayed in the correct language, but then the cart and checkout pages are only shown in English, even though I created translations for those pages, adding the same shortcode for each language version.

Please check and let me know how to fix this – this is a huge obstacle and we need this fixed ASAP in order to be able to launch the website.

Thanks
