Good day, Monica1991.
Allow me to share details that can explain where the gains or losses are coming from.
A loss or gain is an effect of a home currency adjustment in QBO. This type of adjustments change the home currency value of your foreign balances, recalculating them based on a new rate. It also affects your balance sheet accounts.
To see more details or where the losses or gains are coming from, open your Profit and Loss report or Balance Sheet. Then select the amount displayed on the report for the account you're reviewing to open the Transaction Report for that account.
If the account has open transactions (such as an invoice) and you ran at least one Home currency adjustment, the Transaction Report displays additional rows for journal entries that show the date and exchange rate at which you revalued your Foreign currency. These journal entries display 0.00 (as explained in the previous section).
The total unrealized gain or loss appears in the row for each of your open transactions so you can easily see how all Home currency adjustments affect this transaction.
In addition, the Profit and Loss Details report displays 0.00 journal entries in the Exchange gain loss section to provide you with more details on exchange rates and revaluation dates that do not affect your books.
Additional details about this are discussed here:
If you haven't made any adjustments, I recommend reaching out to our chat or phone support agents. They can take a closer look at this and determine why there are gains or losses even if you're using the same currencies. Go to this article to get their contact details: QuickBooks Online Support.
Let me know if that answers your question why there are gains or losses. Please don't hesitate to always get back here if you still have more questions for us.
