6x7 Piston Elevator Up+Down Function [Vid Tutorial!]

I built this elevator exactly the way it's shown, but the topmost piston keeps extending, even though it's not supposed to. Because of this, the sticky piston behind it can't pull it back into the wall.I checked every block, piston, and redstone unit and figured out that the redstone dustdirectly below the torch behind the upper descend button (the button that allows you to go back down the elevator from the top floor) is receiving power from said torch and powering the block next to the piston, therefore keeping it on. When I push the button, the piston retracts, but extends again when the button is no longer pressed. How do I fix this??

im totally using this elevator in my hotel all the credit goes to you in the hotel elevator.

why you don't make an elevator with command blocks like me????
only 13 people made download of my elevator, but if you made one, because it was you, people will give tons of downloads!(And command block systems are smaller, more practical and easier to make).

how to download the map?

t-flipflops are currently brocken because of the new button timings.

what version of that minecraft?

Pistons are bugged. That's why this elevator, like others not working properly! Btw. I can not find that elevators.

Hey I always get stuck in the pistons. Also not all the pistons retract. Any help?
