Just discovered that something was not done correctly during 2016 currency revaluation QB. Was it a system bug then? AR is NIL but still show an outstanding now

Hello @QB Beginner,

Welcome to the Community. I'm here to help you with your currency concern in QuickBooks.

Unrealised gains happen when there are changes in exchange rates. I've checked here and I haven't found any system bug during that time.

I recommend reviewing the Transaction Detail report to know more about your unrealised gains or losses in the system.

Here's how:

1. On the left navigation bar, click Reports.
2. Scroll down and select Transaction Detail by Account.
3. Filter the date range.
4. Review the transaction.
