Water cauldron has lava texture with really low brightness or contrast.

I just made a world to play with cauldrons but when i just started putting water in a cauldron i saw lava texture with really low brightness or contrast i put more caulrons with water THE SAME! so i closed minecraft then opened again The same THING! so idk what is that.

EDIT: i loaded up a brand new world and a random seed by the game still the same issue

ANOTHER EDIT: but when you dye the water with this weird low contrast or britghness lava texture it becomes the normal water texture with the color of the dye
