QnA not working properly

Hi,

I’m trying to build a small chatbot to test some features and I don’t if is a bug or if I’m making something wrong but this thing is annoying me.

I’ve created 2 QnAs and doesn’t matter what I text to the chatbot he always answers one of these two options even if the text doesn’t look alike at all. What I want is, if the QnA doesn’t exist return None so I can handle on the Flow.

Here’re my two QnAs

And here is the chatbot behavior


There is something I’m missing?
