Jar of Tomato Sauce Separation at Bottom of Jar (Imgur Pics)

Hi all, does anyone know why there is a pale layer separation in this jar of tomato sauce?

Does something in the canning process cause some sort of natural separation?

(I have a jar of Costco marinara and there’s no separation like this at the bottom of that jar)

Thanks in advance to all who reply!!
