From what I see the flag is setting the amount of time the door will be moving. So why do you have the garage on for 2 seconds in block 11?
Get rid of the garage off, change the 2 seconds to 1 second.
So then the door will be activated in block 10 along with the flag. After 2 seconds, the flag is off which will activate the door again, this time stopping it since the opener is just a toggle.
Should do it.
