[Resolved] Accordion content did not translated in French in WPML

Background of the issue:
I am trying to translate the FAQ section on my website using WPML. The site I need help with is hidden link. I have been following your documentation to achieve this.

Symptoms:
The accordion content in the FAQ section is not translated into French. Only the title is translated, but the side accordion content is not.

Questions:
Why is the accordion content not translating in WPML?
How can I ensure the entire FAQ section is translated, not just the title?
