[Resolved] Astra theme footer widget are not included into Strings translation

Background of the issue:
I am trying to translate my headings and texts on the footer using WPML with the Astra theme. I have checked WPML advice in a tutorial and been in touch with the Astra developer, but no advice has led to a resolution. Here are my two language versions: hidden link and hidden link. I have tried updating the theme, switching off the cache plugin, and using WPML > String Translation to find text related to the Astra theme. I have also checked this guidance: https://wpml.org/forums/topic/i-dont-know-how-to-translate-footer-widgets/ and https://wpml.org/documentation/getting-started-guide/string-translation/finding-strings-that-dont-appear-on-the-string-translation-page/. It's the second website where I have encountered issues translating Astra footer widgets with WPML.

Symptoms:
Footer widget strings are not included in the translation list. Specifically, the headings of the sections on the footer and the description text on the footer are missing.

Questions:
Why are the footer widget strings not appearing in the WPML String Translation list?
How can I resolve the issue of translating Astra footer widgets with WPML?
