I wish you didn't have to go through all these hurdles with invoice templates, @bitboyenterprises. Rest assured I'm here to help address your concern and point you in the right direction of support to sort this out.

To begin with, we can utilize the Verify and Rebuild Data tool. This way, we'll be able to identify and resolve the most commonly known data issues within your company file.

Before proceeding, let’s ensure we always have our QuickBooks Desktop to the latest release to keep your software up-to-date so you always have the latest features and fixes. Then, create a backup company file to secure your data if you ever run into problems.

Follow these steps on how to verify data:

1. Choose Window, then Close All.
2. Go to the File menu, and then click Utilities.
3. Select Rebuild Data.
4. Follow the onscreen instruction to back up your data.
5. When the tool finishes, select OK.
6. Navigate to the File menu, then click Utilities.
7. Click Verify Data, then select Rebuild Now once QuickBooks finds an issue with your company file.

If the same thing happens after trying those steps, I'd recommend reaching out to our QuickBooks Desktop Support Team. This way, they'll be able to check your account in a safe environment and do an investigation regarding this query. Please check our available hours to ensure that we address your concern promptly.
