If this isn't the case, then the full cache in your browser might be causing this unexpected QuickBooks behavior. I have a different set of steps to resolve this.
To start, please log in to your account using a private window or an incognito. This can help determine and isolate browser-related issues since it doesn't store any cache data.
You can use the following shortcut keys below to access one:
Ctrl+ Shift + N for Google Chrome .
Ctrl + Shift + P for Mozilla Firefox and Microsoft Edge .
Command + Shift + N for Safari .
After that, please select the right Payee for your transactions again. If it works fine this time, please go back to your regular browser and clear its cache. This helps to restore the default setup of the browser and refresh the system.
If the issue persists, you can use another supported browser instead. This helps make sure you'll get the best and most secure experience with the program.
