Object changes position/rotation, when moved (in/out of parent) in the heirarchy in the editor!

Hey, when I move my object up a level in my heirarchy, it's position changes. when I move it back into it's previous parent, the position resets to the correct state. This is happening wether I'm in play mode or not. Due to confidentiallity, I can't share my project, unfortunately.

Is there a way I can "lock" it's world position/rotation/scale so it doesn't change?

EDIT: For now, I've "fixed" my issue by rebuilding the problematic part of the scene, but I would still be interested in knowing if there is such a lock for future use.
