armor texture transparency issue (but just in specific case)

im using Mcreator 2021.1 and Forge 1.12.2 generator i created an water armor, that are a cyan semi-transparent overlay on player, it works but if player have item on left/right hand it get opaque

i created depuration item that are invisible and it still get opaque, and other thinks work correctly, i think is Hand.item animation

someone know how to solve it?
