[Решено] widget String translation not showing in front end

Background of the issue:
I am trying to resolve an issue with WPML where string translations for a widget are not showing on the front end. I added new items to a widget and modified the XML code to include these new items, but the translations still do not appear. This is a recurring issue similar to one I had before, as discussed in this forum thread: https://wpml.org/forums/topic/some-strings-translation-are-not-updating-on-the-website/. The site I need help with is скрытая ссылка.

Symptoms:
String translations for a widget are not showing on the front end despite adding new items and modifying the XML code.

Questions:
Why are the new widget item translations not showing on the front end?
What steps can I take to ensure the translations update correctly?
