[Risolto] Automatic Translation Problem

Background of the issue:
I am trying to translate a WordPress website using the automatic translation tool provided by WPML. I have reviewed the first page and noticed issues with the translation process.

Symptoms:
Not all strings on the page are translated. When attempting to edit the translation, it appears that some strings are not collected for translation.

Questions:
Why are some strings not being translated automatically?
How can I ensure all strings are collected for translation?
