Why does my pause & quit menus appear when I load next level?

When I start my game the menus work as they are supposed to. They are not visible because I have quitMenu.enabled = false; and pauseMenu.enabled = false; at void Start () in code.

It's when I start the next level that my pause menu and exit menu appear at the start of the level even though they are set to false in code. I have looked over this repeatedly and couldn't find the reason. I figure now it's time for a fresh pair of eyes to take a look.

All the functionality works with the exception of the menus appearing at the start of the next level loaded. Also when I go back to the Main Menu the menus aren't visible as they should be because they are set to false in code. I am using the same assets in both scenes with exception of the pause menu, which isn't in the starting scene, but the next scene loaded. I don't get why the code works in the starting scene but not the next scene loaded. Any sort of help would be appreciated.

Here is the code as it stands:

using UnityEngine;

using UnityEngine.UI;

using System.Collections;

 public class menuScript : MonoBehaviour 
 {
     public Canvas quitMenu;
     public Canvas pauseMenu;
     public Button startText;
     public Button exitText;
 
     // Use this for initialization
     void Start () 
     {
         quitMenu = quitMenu.GetComponent<Canvas> ();
         pauseMenu = pauseMenu.GetComponent<Canvas> ();
         startText = startText.GetComponent<Button> ();
         exitText = exitText.GetComponent<Button> ();
         quitMenu.enabled = false;
         pauseMenu.enabled = false;
     }
     
 
     public void ExitPress() 
     {
         quitMenu.enabled = true;
         pauseMenu.enabled = false;
         startText.enabled = false;
         exitText.enabled = false;
     }
 
     public void NoPress()
     {
         quitMenu.enabled = false;
         pauseMenu.enabled = false;
         startText.enabled = true;
         exitText.enabled = true;
         Time.timeScale = 1;//unpauses game
         AudioListener.volume = 0.5f;//unmutes sound
     }
 
     public void StartLevel()
     {
         quitMenu.enabled = false;
         pauseMenu.enabled = false;
         Application.LoadLevel (1);
         Time.timeScale = 1;//unpauses game
         AudioListener.volume = 0.5f;//unmutes sound
     }
 
     public void MainMenu()
     {
         Application.LoadLevel (0);
         Time.timeScale = 1;//unpauses game
         AudioListener.volume = 0.5f;//unmutes sound
     }
 
     public void PauseGame()
     {
         pauseMenu.enabled = true; 
         //gameObject.pauseMenu.enabled = true;
         Time.timeScale = 0;//pauses game
         AudioListener.volume = 0;//mutes sound
     }
 
     public void ResumeGame()
     {
         pauseMenu.enabled = false; 
         Time.timeScale = 1;//unpauses game
         AudioListener.volume = 0.5f;//unmutes sound
     }
 
     public void ExitGame()
     {
         Application.Quit ();
     }
 
 }
