Hi @tangerine460,

You'll want to clear your app data refresh the program. Let me guide you how.

1. Go to the hamburger menu ☰.
2. Select Help & Feedback.
3. Click Refresh Data, then Refresh.

After following the above steps, power down and restart your device. Then, check if you're still seeing the paid invoices. If you're getting the same results, please contact our QuickBooks Customer Care Support  so we can investigate further.

You can learn more about troubleshooting the app at this link here: Troubleshooting Quick-Start Guide for the QuickBooks Online app. We also a guide on manage customers and income that I'm sure you'll find helpful.
