Item States Dont Work

In my mod, in item states, whenever I try to set the "damage >= 0" to a different number, it doesn't accept it. I've tried doing it with the "damage false" set to true, but that doesn't work either.

After doing some testing, it seems that the highest number you can set the "damage >= 0" to is 1.

I would love for this to be fixed, as without it, I might need multiple items or custom code to change the models and textures.

Any help would be greatly appreciated!
