Power Bi Report Builder | Limited Rows in Sub Reports

I am unsure if this is a limitation of the Power BI service or not, but any advice would be greatly appreciated.

Synopsis:
Using Power Bi Report Builder's sub-reports, we can select an account in a top-level report and pass parameters to display related information via sub-reports. If we load 42 or more rows in any one subreport, the workspace will refuse to display the data after it loads the rows.

In this case, we made a simplified version that has only 1 sub report that contains 84 rows. The other row is the name of account on the Top-level report.

Notes:
The sub-report will load as long as there are less than 42 rows in each sub report in the Top-level Report.

When there are more than 42 rows we are able to pull the data without issue from the backend.

Thank you, - Ian
