I wish I could make it better, @CCCBuilder. Let me make it up to you and offer other ways to get back this feature.

We haven't received reports from other customers, like you, whose having issues working with alternate line shading of the sales form transactions. Let's repair QuickBooks to determine the reason why this feature is not working as expected. I'll show you how.

First set:

1. Download the QuickBooks Tool hub.
2. Open and install the downloaded file.
3. On the QuickBooks Tool app, select Program Problems.
4. Click Quick Fix my Program.

Second set:

1. Go to Start.
2. Select Control Panel.
3. Under Program and Features, select Uninstall a Program.
4. From the list of applications, select QuickBooks.
5. Select Uninstall/Change.
6. Click Repair.

Once done, restart your desktop first before working again with QuickBooks. Then, review and reprint the invoices in question to check if they're now showing the alternate line shading feature.

I'm adding this article with the topics you can use while recording the common customer transactions: The Customer Transaction Workflows in QuickBooks Desktop.
