How to remove the ghosting effect on the final image?

Question

I was given three images which are R, G, and B images. I used split to put the RGB into the channel and merge it into one final image. However, I am getting a ghosting effect.

Here is how I did this.

IMAGE_PATH = 'was on local'

def readRGBImages(name: str):
    R = cv2.imread('{}/{}.jpg_r.jpg'.format(IMAGE_PATH, name))
    G = cv2.imread('{}/{}.jpg_g.jpg'.format(IMAGE_PATH, name))
    B = cv2.imread('{}/{}.jpg_b.jpg'.format(IMAGE_PATH, name))
    return R, G, B

def mergeRGB(R, G, B):
    _,_,r =cv2.split(R)
    # plt.imshow(R)
    _,g,_ = cv2.split(G)
    # plt.imshow(G)
    b,_,_ = cv2.split(B)
    # plt.imshow(B)
    orgional = cv2.merge([r,g,b])
    plt.imshow(orgional)
    orgional = cv2.cvtColor(orgional, cv2.COLOR_BGR2RGB)
    return orgional

R, G, B = readRGBImages('3')
cv2.imwrite('3.jpg',mergeRGB(R,G,B))

This is my result:
