This could just be me being stupid and not realizing a really simple mistake but in my mod the texture for the lifesteal sword is still just a diamond sword and its texture isn't overwritten. Once again it could just be me and not the library but I thought to ask the library since it could be something im doing wrong.

Does anyone know why this is happening?

Just to make sure: you ran /polymer generate-pack right?
I fee like thats the easiest way to mess this up (ask me how i know)

I used /polymer generate-pack and the name is there and so is the tooltip, yet the texture doesn't update, I went through the resource pack and the texture is there and i can give myself a regular diamond sword with the custom model data of the life steal sword and the texture looks like the life steal sword.
