My EMH Plan isn't Utilizing the Extra Hour

For some reason when I create a plan and evaluate it for Magic Kingdom on 25th August 2017 it isn’t using the Extra Morning Hour, my first attraction is giving a wait time of 58 minutes. I have selected Utilize the hour and started my plan time at 8am, but, it still won’t work. Does anyone have any ideas why this is?

It is definitely an Extra Morning Hours day.

Never mind, I’ve realised the ride isn’t open for EMH.
