Pygame Collison Detection - Only detects in top left corner

Question

My problem: I have created a level map and tried to implement some basic collision detection. I have blocks which I named dirt_bg And I got the blocks rect with the .get_rect function and set its name to dirt_rect

But when I do self.rect.colliderect(tile.dirt_rect) - inside the player class- it only detects collision on the top left corner

Useful info: I have a Tile class where I create the level map I have a player class where I work with characters

Code: class Tiles(pygame.sprite.Sprite):

def __init__(self):
    self.offsetX = 0
    self.offsetY = 0
    pygame.sprite.Sprite.__init__(self)
    global dirt_bg
    dirt_bg = pygame.image.load("dirt_block.png").convert_alpha()
    dirt_bg = pygame.transform.scale(dirt_bg, (102, 102))
    dirt_bg_rect = dirt_bg.get_rect()

    global coin
    coin = pygame.image.load ("1.jpg").convert_alpha()
    coin = pygame.transform.scale(coin, (52, 52))

# coin = pygame.transform.scale(coin,(32,32))

def tile_maker(self):
    rects_tile = []
    y_position = 0
    for row in level_map:
        x_position = 0
        for tile in row:
            if tile == 'X':
                screen.blit(dirt_bg, (x_position * 102 + self.offsetX, y_position * 102 + self.offsetY))

            if tile != 'X':
                rects_tile.append(pygame.Rect(x_position * 102, y_position * 102, 102, 102))
            if tile == 'C':
                screen.blit(coin, (x_position * 102 + self.offsetX, y_position * 102 + self.offsetY))
            if tile != 'C':
                rects_tile.append(pygame.Rect(x_position * 102, y_position * 102, 102, 102))
                x_position += 1
            y_position += 1

Would appreciate any help
