Order details and email address format output, and on hold email payment

Hello there, sorry if double post, but none of the solutions working, even after I searched at google.
I got woocommerce installed at local PC, for setup and testing purpose till I make it online, and I have added custom fields at Billing Address and check out page.
My problem is how to display it at billing/order details page, my custom field are “billing_address_3 and shipping_address_3”

as for my code for output like below:

function woocommerce_custom_address_format( $formats ) {
    $formats[ 'ID' ]  = "{name}\n{address_1}\n{city}\n{address_2}\n{state}";
    return $formats;
}

I want to add the billing/shipping_address_3 right after {address_2} ( for example: {address_2}\n{address_3} ) for both pages according to the last input for each page.

The other problem is, how to remove BACS payment details from customer on hold email?

Thank you.
