Armor breaks after exporting mod (SOLVED)

I have made several armor pieces with custom models and when I test it inside of mcreator it works perfectly fine however, when I export the mod for distribution, the armor uses the default model

Here is what it looks like before export: https://drive.google.com/file/d/1baaxv0CeIeezCCiSVhGTTSaAntExGddS/view?usp=sharing

If anybody knows how to fix this please help

EDIT: I figured this out. Using optifine is what was causing the issue
