problems displaying chosen payment

Hello. I installed the plugin and everything works normally, except that the payment methods do not appear in the email to the customer. Here we use (pix, boleto, pagseguro, mercadopago, etc.). I’ve seen the tool and the WCHook video but it only shows bank details. Does not show other payment methods. I have this problem to use the plugin, because the customer needs to receive the bank slip or the pix data for payment.

The plugin i´m using is: PIX.
