Welcome back to the Intuit Community, @RenoDavid.  

Thanks for sharing the results of following the steps from @Charies_M.

Before contacting our Technical Support Team, I have another troubleshooting step you can try for the unclassified transactions to show as classified.

To begin, run the Rebuild Data tool to repair the problem in your QuickBooks company file. Next, perform the Verify Data Utility tool to check for damaged file items.

For detailed instructions, follow the steps below.

1. Open your company file and click on the File menu.
2. Choose the Utilities tab, then select Rebuild Data.
3. In the Rebuild Data window, hit on the OK button to continue.
4. Create a backup copy of the data file to avoid accidental loss and select OK.
5. Once the backup file is successfully saved on your desktop, the data rebuild process will start automatically.
6. After completing the process, the application will display Rebuild has completed.
7. Click OK.

Next, run the Verify Data tool to check for the remaining data damage. From the link I attached, go directly to Step 2 for detailed instructions.

If you continue to get the same result, I recommend contacting our Technical Support Team for further assistance. Since you're unable to see the pop-up window to view the contact information, press F1 on your keyboard to display the Help window.

To get the detailed information on how to reach them, check out these steps.
