Some things dont reset when I want them to

So me and my friend are trying to make a little maze game together (we are both beginners to coding and unity) where you control a player and have to navigate towards the end of the level. After each level we use SceneManager.LoadScene (currentlevel); with a variable, and the same when the player "dies". However, on of the obstacles is supposed to be a long wall that fallows the player down the Z axis, and kills the player if they collide, or the player messed up and hits another obstacle. What happens though is when I reload the scene, my wall does not get reset to its original position. I was wondering if there was any way to fix this?
