We can try running the Custom Transaction Detail Report to see all the vendor names. Running Custom Transaction Detail report can show the list of the vendor you have on a specific period, paid date, amounts, and the class. I’ll show how:

1. Go to the Reports menu, then Custom Reports.
2. Select Transaction Detail.
3. Click Customize Report
4. Go to Filters and choose Name. From there, select the vendor names. 
5. Press OK.

You might want to check this article about customizing vendor reports in QuickBooks. This helps you modify some information based on your business needs. If you want the same settings or customization to be available for future use, just create memorized reports. QuickBooks saves it, so you do not have to go through the customization process again.

If it works, try running the repair tool to help resolve odd behavior when running the vendor balance report. Let's create a backup company file first just in case you ever run into problems. We can use your backup to restore your data. Here's how to repair the software: 

1. Restart your computer.
2. Go to the Windows Start menu, and then pick the Control Panel.
3. Tap Programs and Features and then Uninstall a Program.
4. Choose QuickBooks and then Uninstall/Change.
5. Press Continue or Next.
6. Hit Repair and then Next. Note: The repair should start right away, but it may take a while to finish. You can leave it running and come back once it's done.
7. Click Finish when done.
8. Restart your computer to complete the repair.
9. Ensure that your QuickBooks Desktop is updated to the latest release.
