Values of a game object's children change when not supposed to

I have game objects as buttons to go in a certain level in a level select scene. I made a custom editor for a script that the buttons have. The custom editor draws a default inspector and adds a button that executes a function to change the values of it's children.

After I click the editor button and after it sets the values of it's children, I save the scene and open another scene. When I go back to the level select scene, the values of the button game object's children change back.

This might be a glitch, is there any way to fix this.
