Closed vertical iron gate letting units trough...

[Retria]

At start of the game is my vertical iron gate closed, but when I open and close it with trigger, units can get trough closed gate.... why?

The trigger is just most basic:

• north1 gate open
  • Events
    • Player - Player 7 (Green) types a chat message containing -open as An exact match
    • Player - Player 6 (Orange) types a chat message containing -open as An exact match
  • Conditions
  • Actions
    • Set Gate1 = (Current life of Iron Gate (Vertical) 0082 <gen>)
    • Set Gate2 = (Current life of Iron Gate (Vertical) 0079 <gen>)
    • Destructible - Open Iron Gate (Vertical) 0082 <gen>
    • Destructible - Open Iron Gate (Vertical) 0079 <gen>
    • Destructible - Set life of Iron Gate (Vertical) 0082 <gen> to Gate1
    • Destructible - Set life of Iron Gate (Vertical) 0079 <gen> to Gate2

• north1 gate close
  • Events
    • Player - Player 7 (Green) types a chat message containing -close as An exact match
    • Player - Player 6 (Orange) types a chat message containing -close as An exact match
  • Conditions
  • Actions
    • Set Gate1 = (Current life of Iron Gate (Vertical) 0082 <gen>)
    • Set Gate2 = (Current life of Iron Gate (Vertical) 0079 <gen>)
    • Destructible - Close Iron Gate (Vertical) 0082 <gen>
    • Destructible - Close Iron Gate (Vertical) 0079 <gen>
    • Destructible - Set life of Iron Gate (Vertical) 0082 <gen> to Gate1
    • Destructible - Set life of Iron Gate (Vertical) 0079 <gen> to Gate2

And I am not using it in any special way:

How I used my iron gate

And I changed only HP of gate, nothing else!

I am uploading map too, but I belive I did not make anything coliding with gate....

I tried google this issiue and was surprised nobody had this problem yet? :O
