The parity issue:

You use resin clumps for armor trims instead of resin bricks, unlike what was supposed to happen in Java. From the Java 24w45a changelog:

• Resin Brick is now used as the material for armor trimming instead of Resin Clump

Steps to Reproduce:

1. Get a netherite chestplate.
2. Get any armor trim.
3. Try to use resin bricks as the trim material - It won't work
4. Try to use resin clumps as the trim material - It works

Expected Result:

Resin bricks are used for armor trims instead of resin clumps, like what was supposed to happen in Java. 

Observed Result:

Resin clumps are used for armor trims instead of resin bricks.
