An issue with getting textures and item names to properly display

[neon-gr33n]

All the items, blocks and fluids included with this example (excluding the 'safe falling' enchantment book) display without textures and are substituted for the default placeholder texture (pink and black checkerboard square with the item name displayed over it) In addition to this apparent issue, the actual text for item simply will not display correctly. item sword extended for example, shows up as item.sword_extended.name. and cow hide as item.cowhide.name. I'm wondering if there is any way to resolve this issue? Thanks in advance.

I'm going to bump this because I am having the same sort of issue.
