I'll work with you to resolve this reporting error you have in QuickBooks Online (QBO), @2kids2dogs. This way, you can manage your checks and vendor transactions accordingly.

This transaction report error can sometimes be caused by the browser's overtime collection of data from frequent page visits. To isolate this matter, you can perform some troubleshooting steps.

You can start by pulling up your QuickBooks Online (QBO) account using a private browser (incognito). Here's how:

• Press Ctrl + Shift + N (Google Chrome)
• Ctrl + Shift + P (Firefox)
• Control + Option + P (Safari)

Once signed in, go to the Reports menu's Standard tab to pull up the Transaction List by Vendor report. Then, customize it to focus on one specific vendor. Please see the screenshot below for your reference.

If you're able to do so, return to your default browser and clear its cache. This will refresh the system and remove older data that causes viewing and performances issue. However, if this matter continues, I'd recommend using other supported browsers.

Also, you can save the said report's current customization settings and export it to an Excel file for future use. To do so, I'd recommend checking out these articles for the step-by-step guide:
