Yes, sure, @Kroberts210.

I appreciate you for providing the detailed custom error message. I'm here to ensure you can get rid of the custom report pop-up message in QuickBooks Online. So, let me share with you some tips or troubleshooting steps about scheduling and customizing a report. 

The report's pop-up message will appear if you use Custom in the Report period. With this, I'd recommend selecting the Weekly, Last Month, or This month when customizing the reports. This way, the custom pop-up message will stop showing up and you can get the automated report that you want. See the sample screenshots below for your reference. 

For more details, check out this article: Set schedule and email information for a memorized report.

Additionally, you have an option to add a memorized report to a group. Grouping reports allows you to organize them in your lists. For the complete details, visit this page: Memorize reports in QBO.

Lastly, feel easy to click this link about how to set up general report preferences, print, email, and export reports: Run reports in QBO.

Let me know in the comment section if you have further questions about your reports. I'm glad to help. Take care.
