[Résolu] Not everything is translated

Background of the issue:
I am trying to translate my frontpage using WPML, but not everything is translated. I followed the guide at https://wpml.org/forums/topic/wpml-doesnt-translate-some-elementor-widgets/ but encountered issues saving the XML code. Additionally, I noticed formatting differences on translated pages like lien caché. I also see duplicate language variations under WPML - Translation management - Pages, even when filtering for Danish.

Symptoms:
The frontpage is only partially translated, with minor elements like MailChimp being translated. I can't save the XML code, and some pages are formatted differently in translations. Duplicate language variations appear in the translation management section.

Questions:
Why is my frontpage not fully translated?
Why can't I save the XML code?
Why are some pages formatted differently in translations?
Why do I see duplicate language variations in translation management?
