Hi @tkwing009,
Apologies for the delay in getting back to you on this.
Can you tell us which other plugin you are using for the delivery date info?
Also, we do have a filter to remove certain fields from the Invoice. You can refer to this example code snippet that will help you with this:
/**
* Add this code snippet in functions.php file of your currently active theme.
* An example that removes the 'Payment Method' field.
*/
function example_removed_payment_method( $fields ) {
unset( $fields['payment_method'] );
return $fields;
}
add_filter( 'wcdn_order_info_fields', 'example_removed_payment_method' );
In the above snippet you can add the field that you want to remove from the Invoice instead of the Payment Method field.
Kind Regards,
Upendra.
