When Multiple Fire Textures Are Present, Additional Fire Textures Are Invisible

I just wanted to burn down trees to make my world a flat world, but as you can see, their might be too much Fire, because it doesn't show some of the textures for Fire.

(This might be a separate bug, but on the 3rd picture, it SEEMS as there are leaf blocks, but when said [chunk?] updated, it revealed no leaf blocks were present.)

(They were burned completely, but didn't VISUALLY show that.)
