Modify a camera behavior

Hello,

I want to modify my camera behavior for it to stay on the same Y axis range (with 3 states left middle and right)

So I made this:

But the camera was still acting on his own when I was modifying its position (I noticed by detaching the spring arm from the pawn)

Should I always detach it ? Is there a simpler way than that ?

-130, 0 and 130 will be used in world axis.
Convert them to world or use set relative location.

Thats not my question and I know what you mean but its not a problem since my character is always on the same Y axis

Ok, elaborate what you mean by acting on its own.
