When I click on that little clock I get a popup with a message about "scheduled bills or deposits due."
.

Clicking on that message shows me that there are indeed several bills that are "DUE SOON" in the BILLS & INCOME list, but they are already entered into the register so I don't know what action I need to take.
These are reminders that the payee will automatically pull the money owed from my checking account or credit card. In other words, they are set up as "auto pay" with the payee and there is no further action I need to take.
If I exit Quicken and then re-open it the little clock is gone and the "DUE SOON" notices are gone from the "BILLS & INCOME" list. Is there something I can do to clean this up without restarting Quicken?
Is there anything I am supposed to do about those bills or deposits that are due?
