I am having a schedule overlapping problem. Refer to the link, see the 6th, and try to book a “1 acre lawn”, which is a 5-hour job, yet there is only 1 free hour of time left. Changing the time slots has no effect. See more of the overlapping issue on the 7th. https://www.grassguy.net/schedule-a-cut/
On the 7th there wouldn’t be time for the 2nd appointment.
