Hi there JoJo79,
Thanks for reaching out about your reports. QuickBooks Desktop is a great tool able to help you keep track of sales and expenses so you can see the profit of your business. I can point you in the right direction for assistance with these reports.
For help with these reports going blank after selecting to omit a product, I recommend reaching out to the QuickBooks Dekstop support team outside of the Community. They'll be able to view the report you've generated with you in a secure setting to assist in getting all the information to display correctly. You can reach out to them using the methods outlined in the QuickBooks Desktop software support policies.
If you have any other questions, feel free to reach out here.
