Image buttons not working properly (pygame)

Python

Hi I don't know if anyone can help me I'm quite new to coding and I have come across an issue with my menu I am creating , basically when I choose an option such as audio it also hits my mute button which is behind it but on the next screen (audio options menu) so it mutes the game without me choosing that option , this issue also happens with other buttons.

this is my code for the game loop

import pygame
import button

pygame.init()

#create game window
SCREEN_WIDTH = 800
SCREEN_HEIGHT = 600

bg_img = pygame.image.load("D:\Python\Projects\Second_menu\yper_saber_no_buttons.png")
bg_img = pygame.transform.scale(bg_img,(SCREEN_WIDTH, SCREEN_HEIGHT))

screen = pygame.display.set_mode((SCREEN_WIDTH, SCREEN_HEIGHT))
pygame.display.set_caption("Main Menu")

pygame.mixer.init()
pygame.mixer.music.load("D:\Python\Projects\main_menu\High_Contrast_-_If_We_Ever.wav")
pygame.mixer.music.play(loops=-1)

#game variables
game_paused = True
menu_state = "main"


#define fonts
font = pygame.font.SysFont("arialblack", 40)

#define colours
TEXT_COL = (255, 255, 255)

#load button images
start_img = pygame.image.load("D:\Python\Projects\Second_menu\Start_Button.png").convert_alpha()
options_img = pygame.image.load("D:\Python\Projects\Second_menu\Options_Button.png").convert_alpha()
quit_img = pygame.image.load("D:\Python\Projects\second_menu\Quit_Button.png").convert_alpha()
controls_img = pygame.image.load("D:\Python\Projects\second_menu\Controls_Button.png").convert_alpha()
audio_img = pygame.image.load("D:\Python\Projects\second_menu\Audio_Button.png").convert_alpha()
video_settings_img = pygame.image.load("D:\Python\Projects\Second_menu\Video_settings_Button.png").convert_alpha()
mute_menu_music_img = pygame.image.load("D:\Python\Projects\Second_menu\Mute_menu_music_Button.png").convert_alpha()

back_img = pygame.image.load("D:\Python\Projects\second_menu\Back_Button.png").convert_alpha()

#create button instances
start_button = button.Button(328, 380, start_img, 1)
options_button = button.Button(325, 435, options_img, 1)
quit_button = button.Button(355, 485, quit_img, 1)
#option menu buttons
controls_button = button.Button(304, 373, controls_img, 1)
audio_button = button.Button(304, 473, audio_img, 1)
Video_settings_Button = button.Button(304 ,423, video_settings_img, 1) 
back_button = button.Button(355, 530, back_img, 1)
#audio menu buttons
mute_menu_music_button = button.Button (350, 473, mute_menu_music_img, 1)


#game loop
run = True
while run:

  event_list = pygame.event.get()
  for event in event_list:
    if event.type == pygame.KEYDOWN:
      if event.key == pygame.K_SPACE:
        game_paused = True
    if event.type == pygame.QUIT:
      run = False

  screen.blit(bg_img,(0,0))

  #check if game is paused
  if game_paused == True:
    #check menu state
    if menu_state == "main":
      #draw pause screen butttons
      if start_button.draw(screen, event_list):
        game_paused = False
      if options_button.draw(screen, event_list):
        menu_state = "options"
      if quit_button.draw(screen, event_list):
        run = False
    #check if the options menu is open
    if menu_state == "options":
      #draw the different options buttons
      if controls_button.draw(screen, event_list):
        print("Controls")
      if audio_button.draw(screen, event_list):
        menu_state = "Audio"
      if Video_settings_Button.draw(screen, event_list):
        print("Video settings")
      if back_button.draw(screen, event_list):
        menu_state = "main"
    #check if the controls menu is open **TO DO**

    #check if the audio menu is open
    if menu_state == "Audio":
      #draw the different audio options buttons
      if mute_menu_music_button.draw(screen, event_list):
        pygame.mixer.music.pause()

    pygame.display.update()


pygame.quit()

This is the code for my button.py

import pygame

#button class
class Button():
	def __init__(self, x, y, image, scale):
		width = image.get_width()
		height = image.get_height()
		self.image = pygame.transform.scale(image, (int(width * scale), int(height * scale)))
		self.rect = self.image.get_rect()
		self.rect.topleft = (x, y)
		self.clicked = False

	def draw(self, surface, event_list):
		action = False
		#get mouse position
		for event in event_list:
			if event.type == pygame.MOUSEBUTTONDOWN:
				if self.rect.collidepoint(event.pos):
					action = True
					self.clicked = False

		#check mouseover and clicked conditions
				if self.rect.collidepoint(event.pos):
					if pygame.mouse.get_pressed()[0] == 1 and self.clicked == False:
						self.clicked = True
						action = True

		if pygame.mouse.get_pressed()[0] == 0:
			self.clicked = False

		#draw button on screen
		surface.blit(self.image, (self.rect.x, self.rect.y))

		return action

What I have tried:

i changed from

pygame.mouse.get_pressed()

to

MOUSEBUTTONDOWN
