Slot look up values


I have two very basic questions for look up slot values:

  1. I have NUL sample like this: transfer 5.50 USD from my savings account to my loan account

I need a way to have bot account type entities in a slot - i.e. I need the user to provide both not just the first one

  1. when I run the above in interactive mode I got this: amount: 35.5, currency: [‘USD’, ‘USD’], account_types: [‘savings’, ‘loan’, ‘savings’, ‘loan’], requested_slot: None, session_started_metadata: None

why I got loop up values like: [‘USD’, ‘USD’] what is this exactly - [text, look up match]?

Thank you!

First one is the text from the user, second one is its match from the lookups :slight_smile:
