New lawn day schedule only

I’m trying your schedule, but have a couple of questions. I set it up per your screen shot and the schedule says it won’t start until tomorrow, although I programmed start today. Is that expected behavior?
How does the program know to stop at 7pm?
I did a “Quick Run” and it said it would run for 48 minutes, I let it run past the 2 minutes in the program and then stopped it.
Any clarification / knowledge appreciated.
