Thank you for bringing up the currency revaluation steps you're taking, @bakeronline.
I'm delighted to provide some information on revaluing currencies in QuickBooks Online. This way, I can assist you in fixing the unrevalued currencies.
Please know that we only save one exchange rate per account each day. This exchange rate calculates unrealized gains and losses. This ensures accurate and compliant books. Also, make sure that the dates are correct. QuickBooks automatically creates currency revaluation journal entries with zero values so you can check the date and exchange rate you used. You can no longer edit these entries except the journal entry's number and Memo field.
In addition, the best place to check your exchange gain/losses is on the Profit & Loss, Balance Sheet, Statement of Cash Flows or Customer/Supplier Balance reports. For more information, check out this article: Frequently Asked Questions about Home Currency Adjustments.
Moreover, read the following articles to know how to handle mixed currencies for customers or suppliers and some errors:
