Summary
On the transaction UI page on the admin, we can see the list of all the transactions made on the account. We can see that all the payment methods show the correct currency from the account's country, except in cases of the Giftcards, from the GiftcardHUB connector. If the transaction is made with Giftcard + another payment method, the correct currency is applied. The bug only occurs when the transaction is made exclusively with Giftcard. In this scenario, the currency shown is the Brazilian Real currency (R$), regardless of the country of the account.
This bug doesn't impact on the transactional flow. This means that the transactions made with giftcard are still able to be authorized, approved, captured and finished without problem. It is only a UI problem that can cause confusion to the user of the admin (merchant).
Simulation
Enter the Transaction UI page and filter by Giftcard.
Workaround
As far as we were able to see, there is no workaround for this situation
