Reminder confusion

[Rick Jones]

There are several functions in MyCars that seem to overlap and interact, and I have great trouble understanding how they all work.

There are Events, Recurring Bills, Reminders, Notifications. If I create a recurring bill, then it generates its own reminder. If I want a reminder for a service I have to create an event, which ties into a service item. When these events are triggered I get a notification. What does tapping OK do? Is it supposed to create the related item for the current date?

When I look at the list of events, there are dates against each one, but some are in red, and some have "(OK)" after them. What does that all mean?

There must be some logic to this, but I really don't get it. Can someone please explain?

Thanks!
