Invoice payment method inconsistency

Hi,

When a product is purchased on my store the order is set to processing then an invoice is sent out. The payment method listed here is ‘WooCommerce Payments’ when it should show what the customer used to purchase the order e.g. visa debit card.
If I resend the invoice out manually by going to the order and selecting ‘Email invoce/order details to customer’ in order actions it works correctly and the payment method in the email shows the purchase method like visa debit card.
