“Popular all of time” & “latests Articles” are in Page Builder, which is this can be translate by translating the whole page. The words in Page Builder can’t be translated, the only way to make the words are change when switch language is translate the whole page. This like create new page but in different language.
Start translating the page (you’ve content with main language)
If you translate a page especially for Page Builder Template, you need to switch to default template, then switch back to Page Builder Template again to make the Page Builder works. All you need is to fill the Page Builder modules like previous language.
To make sure the module have posts with active language, you need to translate all your posts to your languages you choose.
Hope this helps,
