Problem: The client was experiencing an issue where the source English text was unexpectedly changing to Chinese when attempting to translate strings from English to Chinese. Solution: We advised the client to change the source language of the strings from English to Chinese and then translate them back from Chinese to English. Detailed instructions on how to change the source language of strings can be found here: https://wpml.org/documentation/getting-started-guide/string-translation/how-to-change-the-source-language-of-strings/ Additionally, we corrected all strings that were incorrectly showing in Chinese and provided a video demonstration for further guidance.
