Hello @itsonlymelee,

I appreciate you for sharing detailed information here in the Community. I know going to each transaction takes too much time so let me help you fix the problem in QuickBooks.

Since the exchange rate updates when toggling the dates, the browser's stored cache may be full. It can cause unusual behavior in the product, like what you encounter with the currencies.

I'd first suggest logging into your QBO account using a private browser. It doesn't store data in the cache. Thus, it's a great way to isolate browser-related issues.

Use these keyboard shortcuts depending on the browser you're using:

• Google Chrome: press Ctrl + Shift + N
• Mozilla Firefox: press Ctrl + Shift + P
• Internet Explorer: press Ctrl + Shift + P
• Safari: press Command + Shift +N

If private browsing doesn't work, use other supported web engine to get the best and most secure experience with the program.

I've also attached an article you can use to make home currency adjustments in QuickBooks: Enter home currency adjustments for your foreign balances.

You're always welcome to post any questions you have in this space. I'll be happy to help you some more. Have a good day.
