Children changes the parents position

I´m making a door and want to rotate it from the position of where the hinges are. I created an empty object which i called "pivot", put it where I want the pivot and place the door as the child to the gameobject "pivot". When I rotate the pivot the door rotates at the correct place. HOWEVER for some reason all of a sudden this stopped working. Whenever I place the door and details as children of the pivot the pivot inherits the position of the door for some reason, and that position is in the middle of the door = The door rotates around itself.

I have done this many times before but for some reason this happened. I must have hit a checbox by accident or something?
