[סגור] String Translations do not display front end if

Background of the issue:
I have been using String Translate with 'Look for strings while pages are rendered' ticked to find front-end elements of The Events Calendar.

When I uncheck this option, the translations no longer render on the front-end, although they are present in the string translation list. Some translations like dates, times, and event details are working. Link to a page where the issue can be seen: קישור נסתר

I have cleared the cache etc. but it still does not render.

Thanks

Symptoms:
Translations do not display on the front-end when 'Look for strings while pages are rendered' is unchecked. Expected translations like 'Aggiungi al calendario' and 'Dettagli' are not appearing, instead, the English versions are shown.

Questions:
Why do translations not display on the front-end when 'Look for strings while pages are rendered' is unchecked?
How can I ensure all translations appear correctly on the front-end?
