Mentioned in today's Preview, all Bricks types should now aligns to each other. However, Mojang partially fixed this bug. Nether Bricks & Red Nether Bricks are still affected by this bug because they didn't fix the bug correctly.

Instead of replacing the current textures in the game file, they ported the Java textures into Bedrock but Bedrock's Nether Bricks & Red Nether Bricks are different.

On Bedrock, the name are "nether_brick" & "red_nether_brick", unlike Java which is "nether_bricks" & "red_nether_bricks".

As you can see below, game files now have two Nether Bricks & Red Nether Bricks textures but only the older one is used because of the name issue.
