[1.10.2] meta item models not loading

Okay, I've finally got back into modding and decided to rewrite my minimal work from scratch to learn stuff again. I've created a meta item with 11 (I think) subitems stored using damage. These are created. However, after trying to set them to have seperate models, the paths are not being followed and every subitem reverts to soundcontrol:discCore#inventory, rather than, say, soundcontrol:discCore_13#inventory (meta/dmg 0)

It's probably a silly mistake, it almost always is. Thanks in advance.
