I am telling you with certainty the video you showed you were doing wrong. You were not using table selector. I have told you the exact problem you are having. Start with the docs
https://botpress.com/docs/cloud/studio/tables/
As far as Cyrillic goes, it probably doesn't work as well with the langauge. And this has NOTHING to do with botpress. ChatGPT is trained on the internet which is is largely english. LLM themselves are better at english right now because that is what they are largely took at data inputs.
Whether or not your specific issue relates to this kind of issue is a mute point because you need to take the time to read the docs, learn how to debug, etc before claiming that the issue is other people.
This is part of being a dev and learning how to use these tools.
