Hi @palomamtnez,

So I've ran into the same issue as you did and here is what I found.

• This is the OrderAdjustment currency converter in Commerce (it doesn't pass the currency to formatter): craftcms/commerce/src/models/OrderAdjustment.php#L115
• This is how the Transaction looks like (when it has defined currency): craftcms/commerce/src/models/Transaction.php#L184
• If the currency is not defined it fallbacks to the base currency (this is just an example for how to configure CurrencyAttributeBehavior): craftcms/commerce/src/behaviors/CurrencyAttributeBehavior.php#L164

This issue will occure when craftcms\commerc\elements\Order->currency has different value other than what is set to base currency.

I think this is the intended behavior on Commerce side but still feels wrong:

This helped the transaction to remain valid when having same currency and payment currency but not the same as base currency:

use craft\commerce\events\TransactionEvent;
use craft\commerce\services\Transactions;

Event::on(Transactions::class, Transactions::EVENT_AFTER_CREATE_TRANSACTION, function (TransactionEvent $event) {
        $tx = &$event->transaction;
        if ($tx->currency !== $tx->paymentCurrency) { return; }
        $tx->paymentCurrency = $tx->currency;
        $tx->paymentAmount = $tx->amount;
        $tx->paymentRate = 1;
});

Do you have currency issue on the transaction tab?
