While I am greeting hi to the bot, it is responding in the way I need it to, as shown in Working Proper image below:

But when i try to greet with other words such as hello, hey, it is taking random value USER as the username or taking the greeting itself as an username.

I don’t understand how different greets have different understandings to take.

Could anyone explain this on rectifying where I am going wrong?

To never skip the collect step in that flow, set ask_before_filling: true in the collect step:

   - collect: user_name
        description: a single letter's string
        ask_before_filling: true
        reset_after_flow_ends: false
        rejections:
          - if: not (slots.user_name matches "^[A-Za-z]+(?:[-' ]?[A-Za-z]+)*$")
            utter: utter_invalid

Thank you so much for your response. Now the bot is trained good and taking different greetings.
