I can help you perform troubleshooting steps to resolve font displays in your Summarize Balance Sheet report, Pennes.

In QuickBooks Desktop, you can first check the display settings of the program to enable clearer font modifications. To do this:

1. Close QuickBooks Desktop.
2. Open the Windows Start menu and type QuickBooks into the search. 
3. Then, right-click the QuickBooks icon and select Open file location.
4. In the folder, right-click the QuickBooks.exe file and click Properties.
5. Go to the Compatibility tab and select the Disable display scaling on high DPI settings checkbox. You may also click Change high DPI settings and then Override high DPI scaling behavior.
6. Once done, select Apply and OK.

You can refer to Steps 2 and 3 outlined in this reference for more detailed information: Fix screen issues in QuickBooks Desktop.

However, if the issue persist, let's run the Verify Rebuild Data tool to help resolve common issues in the program. Here's how:

1. Go to the File menu and click Rebuild Data from Utilities.
2. On the QuickBooks Information window, select OK. Follow the on-screen steps to save a backup.
3. Let the tool repair your QuickBooks file.
4. Once the tool finishes, click OK.
5. Then, from the File menu, click Utilities and select Verify Data.
6. Let the tool check your file for data issues.

Once everything looks good, you may want to export reports to Excel so you can efficiently modify specific details into your overall data.
