clock item being glitch

hey, i have a resource pack with custom model data, im using retextured clocks, but for a normal clock, its a glitched item and i haven no clue why, this is the clock.json file.
{   "parent": "minecraft:item/generated",   "textures": {     "layer0": "minecraft:item/clock"   },     "overrides":      [ 
then it goes down like 40+, and ends properly, runs 
{   "parent": "minecraft:item/generated",   "textures": {     "layer0": "minecraft:artifact/strengthneg1"   } }
thats one of many files, then it rusn the texture, if it has custom model data it works fine, its just the clock normal model, any ideas?
