My failed `failed_test_stories.yml` looks like so:

On line 17, I have a situation where my model/bot works previously well but after implementing newer intents, older ones (line on line 17) fail. What could be the cause?

Secondly, if you observe, on line 10, my intended intent is `statistics` and the predicted is also `statistics`, but I don’t understand why the story failed.

I will appreciate any help
