[Решено] Autosuggest using pages with wrong translation

Background of the issue:
I am creating some pages on my site using the standard page editor. I translated a few products, and now I'm experiencing issues with the auto-suggest feature.

Symptoms:
When I create a link and try to use auto-suggest, it suggests pages from different languages, specifically stuck at Czech suggestions.

Questions:
Why is the auto-suggest feature suggesting pages in the wrong language?
How can I fix the auto-suggest feature to show the correct language pages?
