You may notice that after you've deleted an online payee, the payee reappears in your Online Payee list.
This may happen if your payment processor doesn't allow you to delete online payee information. In this case, Quicken adds the payee back to your Online Payee List. This way, Quicken maintains a complete list of all your online payees.
I hope this helps to clarify!
