Hello wasayw,
Welcome to the QuickBooks community! I love that you're hoping to partner with another service to enhance what you can do with QuickBooks Online. I'll point you in the right direction of getting this sorted out.
Taking a look at Power BI and how it connects with QuickBooks Online, it looks like the integration takes place through the Power BI program. What this means is you connect to QBO through Power BI. Because of that, any errors and mixing of information needs to be looked at with the Power BI team as the integration is handled from their side. Here's the article I found that leads me to this conclusion: Connect to QuickBooks Online with Power BI
I want to make sure you can get your information lining up as it should so you can move forward with your bookkeeping. For support with Power Bi, check out this page: Power BI Support
