Urgent help needed with Null Object

Hi,

I'm working on a Animated Map using After Effects.What I did so far:

- Creating a Null Object

- Creating a camera

- Link Camera to Null Object as a parent

- Set off (with the eyeball) the camera

- Put 3D on at all layers including the Null Object

- Active Camera is on

Then I started making a path for my map. First time I practiced and it was all good. Second time I did it exactly the same as before I ran in this problem:

Everytime I finish making a path with the Null Object and I put on the Camera eyeball again, my whole animation is moving, including the Null Object. Well, this is weird because I'm following a tutorial and nothing happens at his side. Now, it isn't  the problem to move back the animation, but I can't move the Null Object. I tried everything I can possibly imagine.

Please, anyone can help me? I really need to finish this quick.
