Set number of decimals not honored in refund emails

Dear Villatheme Support!

I have set multiple currencies in the plugin and all work properly. One of them is JPY.

This one has a problem. As you know, JPY have no decimals, so I set the number of decimals to zero in the plugin.

This works great for checkout, after checkout, in the woocommerce emails, in the PDF invoices.

BUT it does not work in refund e-mails. There, no matter how many decimals I set, zero or one, it always shows two decimals. This is not great for customers from Japan, that cannot pay with decimals. I am attaching 2 screenshots. One with the order completed and one with the refund email that has the issue.

Please advise! Thank you very much!

Best wishes,
Christian
