Need Help with Custom Rendered Armor and UV maps In blockbench

This is more of a Blockbench problem than MCreator Problem, I'm avoiding posting anywhere else due to the Stigma Mcreator gets in other Forums (unfortunately)

I have created a Custom Helmet in Blockbench whilst following this tutorial https://mcreator.net/forum/51185/tutorial-how-make-3d-rendered-armor-moving-arms-legs-and-head

however I got stuck when trying to export my model as a .Java, To do this in blockbench you must convert your project to a modded entity. And when doing so, It completely Ruins my Helmets UV maps and Rotations. Example ->

How its supposed to Look:

How It looks when converting to Modded Entity:

The UV maps get completely destroyed and they are Unable to be resized, the Texture I used for this Armor is 128x128 Pixels, Any help would be greatly appreciated.
