Rasa2.0.0: Warning for nlu_fallback-Intent

Rasa Open Source

I noticed that the Fallback don’t really works by me.

When I type in some random letters like “sdfasdf” or “blablabla” it recognise them as names with a confidence around 0.91

Is this because of my configurations or because the nul_fallback has only 1 training examples?

(or are this common names anywhere in the world? :sweat_smile:)

my config.yml looks like this:
