[Geschlossen] code module in divi doesn't work with wpml

Background of the issue:
I am trying to use a code module on my website with WPML. When I change the language from English to French or German, the module breaks into code. I also have a widget from Elfsight with a WhatsApp button and a Google review that works fine in English but not in other languages. The issue can be seen on this page: versteckter Link. I expected to see the same module as on the English page: versteckter Link.

Symptoms:
The code module breaks into code when changing the language from English to French or German. The Elfsight widget with a WhatsApp button and Google review does not appear or breaks in French or German.

Questions:
Why does the code module break into code when changing the language?
Why does the Elfsight widget not appear or break in French or German?
