Hi there, Jenn. Thanks for reaching us in the Community. Let me share information about connecting your Power BI in QuickBooks Online (QBO).
Since you've connected Power BI to QBO, you can consider calling their contact support team and ask how the data transfers when connected to QBO. You can also ask why some information on the table is missing and some aren't.
In addition, you can refer to this article to learn how to personalize your reports in QBO: Customise reports in QBO.
Comment on the post if you still have concerns about connecting your Power BI in QBO. I'm always here to help.
