- When display currency is KWD, or BHD data is not formatted correctly in :
$this->adyenDataHelper->originalAmount($notification->getAmountValue(), $order->getBaseCurrencyCode());

- It will always format the amount based on base currency not on display currency and therefore amount is not correctly saved here: \Adyen\Payment\Helper\AdyenOrderPayment::createAdyenOrderPayment

Example:
I place an order for 10BHD but in adyen_order_payment database the amount saved is 100.00 when base currency of the shop is different than BHD, KWD...
Later it crushes the whole flow of generating invoices and capturing the right amount
