Grid height won't change

Hey, i'm trying to make a 128x128 grid but the grid height won't change at all, is this a bug?

Click anywhere on the "View" bar, like grid width or any empty space that is not a button. It's an old glitch where your last changes don't save if you click outside the "View" bar, like the project itself.

Thanks! it worked, i am debted to you :3
