It's great to see you joining this thread, ssander7. I'll share insights to ensure you're able to pay vendor bills in QuickBooks Desktop.

As I've replicated here on my end, the bills that are needed to be paid appeared on the list. One possible reason your bill transaction is not showing on the list, this might be marked as paid. You'll want to verify these transactions to check their status.

If the same thing happens after checking them, I'd suggest running the verify and rebuild data tool. It will help you scan any damaged data and attempt to resolve them. Also, this allows your QuickBooks software to refresh the data inside the company file.
