Basket leaks: defective or not?

I got my first air fryer for Christmas and I love it! It's an ASZ model from Amazon. When I went to wash the basket for the first time, water got behind the window and poured out the bottom. I contacted Amazon about the "defect" and they sent me another one. Just got it, and it has the same seal "defect." This IS a defect, right? I know that liquid shouldn't be cooked in an air fryer, but this seems like a defect and not intentional.. right? I am a newb6so let me know! (I had seen an interesting video showing whole tomatoes, onions, garlic going in to the air fryer to cook/char before transferring to a blender for scratch marinara. I'm afraid to try this recipe because of the leaky basket. )
