Hello again, @itsonlymelee. I appreciate your prompt response.
Right now, QuickBooks Online (QBO) uses the most recent exchange rate from the Markit. Thus, the rate showing in your QBO account changes day by day depends on the new rate. To resolve the issue, you can manually edit the rate if you'd not prefer using the 1:1 exchange rate.
You can see this reference for a guide in manually editing the rate: Enter an exchange rate. Also, to know more how exchange rates work in QBO, take a look at this article: About exchange rates.
If you have further questions about this process, let me know by commenting below. I'm always here for you. Have a nice day.
