[Risolto] The plugin does not translate the whole text, only partially sees it.

Background of the issue:
I am trying to translate text using the plugin (from Russian to Ukrainian). Link to a page where the issue can be seen: link nascosto

Symptoms:
The plugin does not translate the whole text, only partially sees it. On the page link, you will see that only the first section and ONLY the rest of the headings are translated. In the settings, it shows a gear. Added error screens by the link: link nascosto

Questions:
Why does the plugin only partially translate the text?
How can I ensure the entire text is translated?
What does the gear icon in the settings indicate?
Are there any specific settings I need to adjust to fix this issue?
