LOLCATS isn't translated for some blocks/items

Some blocks/items do have the translations 

Examples:

crossbow - crosbowz

debug stick - magik stik

loom - paturn addur

 

yet for some it just doesn't show

Examples:

stone slab

lectern

diorite slab

 

This happens with other languages too, but with slightly different items.

EDIT: shulker shells also don't have translation
