Need Extra Description Field and Hide Pin code

Hi,

I bought the WP Easy Pay Pro to get the custom fields;
Add description
No postcode
Amount default to $0
like this https://squareup.com/terminal/

Can you tell me what I am doing wrong? See here: https://www.zeumic.com.au/credit-debit-card-payment-squ/

Also, can you change my email from [email protected] to [email protected]

Thank you
