External Transaction created a day before bank stmt date shows conversion rate changed in reconciled

Summary:

User creates an external transaction, using a conversion rate of the day before the date of bank statement (due to a Polish law) and then does a manual reconciliation and sees that the external transaction looks correct and then reconciles external transaction with a bank statement.

When he goes to the reconciled tab and looks for reconciled transaction, the value date and the conversion rate is changed.

Is this a functionality? Any inputs please?
