[Решено] Translated ACF fields are not beeing displayed

Background of the issue:
I am trying to get ACF fields to be displayed on translated pages. The issue can be seen on this page: скрытая ссылка. I expected to see the hero slider and the elements below the embed YouTube video as on the original page: скрытая ссылка.

Symptoms:
Translated ACF fields are not being displayed. Instead, nothing is showing on the translated page.

Questions:
Why are the translated ACF fields not displaying on the translated page?
How can I ensure that the hero slider and elements below the YouTube video appear on the translated page?
