Class field is empty on Balance Sheet Report

That is something unusual, @zhenya.

Let me step in and help you out with this. We Install QuickBooks Desktop in its most recent version first. We can keep QuickBooks up to date with the newest features and improvements by doing so. 

I suggest utilizing the Verify and Rebuild Utility tool if the issue persists. The majority of known data integrity problems in your company file will be fixed as a result. Here's how:

1. Go to the File menu.
2. Select Utilities.
3. Click Verify Data then select OK to close all windows.
4. Then, go back to the File menu.
5. Select Rebuild Data under Utilities.
6. QuickBooks will ask to make a backup before rebuilding your company file, select OK.
7. Once the rebuild is done, click OK.
