[Решено] Wpml language switcher

Background of the issue:
I have WPML installed on my site скрытая ссылка and I am trying to add the ability to switch languages via the Language Switcher. I have ensured that the languages are enabled and the content is translated. I have checked the Language Switcher settings and they are configured correctly, with options for displaying the flags.

Symptoms:
The flags for the languages (Greek and English) are not displayed in the menu, even though they are configured in the plugin.

Questions:
Why are the language flags not displaying in the menu despite being configured correctly?
