[Resolvido] Strings not translating

Background of the issue:
We are facing multiple issues regarding string translations that are not showing on the front-end. As an example, in the checkout page, we have a long T&C paragraph that we translated in Chinese yet it still shows in English. We have been using WPML for years on multiple websites and follow your documentations when needed.

Symptoms:
String translations are not showing on the front-end, specifically on the checkout page where a T&C paragraph translated into Chinese still appears in English.

Questions:
Why are the string translations not showing on the front-end?
How can we ensure that the translated strings appear correctly on the checkout page?
