Let's run the Verify and Rebuild tool to fix this, norman.

This tool scans data issues within the company file and self-resolves them. Before proceeding, please note that this may or may not work since QuickBooks 2014 is an unsupported version.

Also, create a backup copy of your company file so you can restore it if some changes occur.

Here's how to verify data:

1. On the top menu, click File.
2. Choose Utilities.
3. Select Verify Data.
4. Click OK if QuickBooks detected no problem with your data.
5. If Verify finds an issue with your data, you'll be prompted to Rebuild Now or View Errors.
6. Click Close or View Errors and take note of the specific error message.

Next, here's how to rebuild data:

1. On the top menu, click File.
2. Choose Utilities.
3. Select Rebuild Data.
4. Click OK if you receive a prompt to back up your company file.
5. Click OK when you get the message, Rebuild has completed, and proceed to the next step.
6. Run Rebuild Data again to make sure there's no error.

If the issue persists, I recommend upgrading to the latest version. Doing so helps you add classes to your checks.

Also, personalizing your Class report in QuickBooks is a breeze. For the detailed guide, please see this article: Run Report.
