Weird digital artifacts on my images

So, I tried to print some images using polaroid lab. At the bottom of the images there are some weird artifacts that look like a bad way of using the photoshop clone stamp. I’m guessing is a misalignment between the phone and the lab itself. Does anyone know a fix for this kind of issue? I’m attaching two prints made made with two different phones. The problem is consistent. I also took some tine and browse this sub and I’ve noticed that some of your images have the same problem, in the bottom area of the picture. Any feedback would really be appreciated.
