Pause Menu back button not working.

Questions & Answers
1

So I am programming a pause menu and everything is running smoothly, however when I click back while in the SettingsCanvas or CreditsCanvas my pause menu disappears like when you click Escape again. I know that the cause is the way I have the code setup for handling opening and closing the Pause Menu. I am just not sure how to go about fixing the problem, as I would like to keep the canvas method of sub menus.

Here is my code.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using UnityEngine.SceneManagement;

public class Pause : MonoBehaviour {

    #region Variables

    public GameObject CreditsCan;
    public GameObject PauseCan;
    public GameObject SettingsCan;

    public string[] credits =
    {
        "AERO",
        "Programming by Stormy Wentworth",
        "Music by Cody Parsons",
        "Copyright (c) 2017 AERO Studios"
    };

    #endregion

    #region Unity Functions

    private void Start()
    {
        StartingCanvas();
    }

    private void Update()
    {
        EscapePressed();
    }
    #endregion

    #region Functions

    public void BackToMenuClicked()
    {
        SceneManager.LoadScene("MainMenu");
    }

    public void CreditsClicked()
    {
        PauseCan.SetActive(false);
        CreditsCan.SetActive(true);
        SettingsCan.SetActive(false);
    }

    public void EscapePressed()
    {
        if (Input.GetKeyDown(KeyCode.Escape))
        {
            if (PauseCan.activeInHierarchy == false)
            {
                PauseCan.SetActive(true);
                Time.timeScale = 0.2f;
            }
            else if (PauseCan.activeInHierarchy == true)
            {
                PauseCan.SetActive(false);
                Time.timeScale = 1.0f;
            }
        }
    }

    public void StartingCanvas()
    {
        PauseCan.SetActive(false);
        CreditsCan.SetActive(false);
        SettingsCan.SetActive(false);
    }

    public void SettingsClicked()
    {
        PauseCan.SetActive(false);
        CreditsCan.SetActive(false);
        SettingsCan.SetActive(true);
    }

    public void QuitClicked()
    {
        Application.Quit();
    }
    #endregion
}

Any help is appreciated.

If anyone else has this issue I figured it out.

You need a function that only runs when you click the back button on your settings, or credits canvases.

 public void BackClicked()
        {
            PauseCan.SetActive(true);
            
            if (PauseCan.activeInHierarchy == true)
            {
                CreditsCan.SetActive(false);
                SettingsCan.SetActive(false);
            }
        }
