[Python] Pygame sprite replication issue [duplicate]

I am making a game and implementing sprites. I have my main (drives game), game_objects (contains sprite classes), game_manager (generates game_objects and adds them to sprite groups), and settings (contains all constant game values). I have managed to generate all the sprite objects that I need and put them into the correct groups. I started to implement the behavior, starting with the paddle sprite, but I am having an issue with the paddle's image. The paddle is drawn at its initial position. The paddle moves with the mouse position. Everytime the paddle moves, it redraws a new image but also keeps the previous images on screen. What I end up getting is a bunch of ghost images that ends up painting across the screen at the paddle's x level. Below is the code I am working with, I am very new to Pygame.

This is the main body:

pygame.init()
active_bricks = []
brick_colors = []
brick_bodies = []

game_screen = pygame.display.set_mode((settings.WIDTH, settings.HEIGHT))
pygame.display.set_caption("SmashCore")
clock = pygame.time.Clock()
game_surface = pygame.draw.rect(game_screen,
(0,0,0), (0,0,settings.WIDTH,settings.HEIGHT))
game_screen.blit(settings.background_img, game_surface)

game_manager.generate_ball()
game_manager.generate_paddle()
game_manager.generate_bricks(active_bricks, brick_colors, brick_bodies)

running = True

while running:
for event in pygame.event.get():
if event.type == pygame.QUIT:
running = False

settings.all_sprites.draw(game_screen)
settings.all_sprites.update()

pygame.display.flip()
clock.tick(settings.fps)

pygame.quit()


This is how the paddle is generated and placed into a group:

def generate_paddle():

paddle_face = settings.paddle
paddle_body = paddle_face.get_rect()
paddle_body.x = settings.WIDTH // 2 - paddle_body.width // 2
paddle_body.y = settings.HEIGHT - 150
paddle_obj = Paddles(paddle_face, paddle_body)
settings.paddles.add(paddle_obj)
settings.all_sprites.add(paddle_obj)

return paddle_face, paddle_body


This is the paddle sprite class:

class Paddles(pygame.sprite.Sprite):
def __init__(self, paddle_face, paddle_body):
pygame.sprite.Sprite.__init__(self)
self.image = paddle_face
self.rect = paddle_body
self.x = paddle_body.x
self.y = paddle_body.y
self.centerx = paddle_body.centerx
self.centery = paddle_body.centery
self.left = paddle_body.left
self.right = paddle_body.right
self.top = paddle_body.top
self.bottom = paddle_body.bottom
self.width = paddle_body.width
self.height = paddle_body.height

def update(self):
pos = pygame.mouse.get_pos()
self.rect.x = pos[0]


These are the values in settings that pertain to the paddle file:

paddles = pygame.sprite.Group()
all_sprites = pygame.sprite.Group()

art_dir = 'assets/art/'
paddle = pygame.image.load(os.path.join(art_dir, paddle_img_path))

WIDTH = 1200
HEIGHT = 900
fps = 60



Below is what is happening in game every time I move the mouse.



I do not know why it is doing this and would really appreciate the help. The movement is fine, I just need it to not keep the old images on the screen. If you could offer a brief explanation of what I messed up that would be greatly appreciated. I am not sure where to even begin.
