My gecko lib item doesn't render properly

the picture shows the broken model, i followed the tutorial built in to the pluggin but when loading minecraft my geckolib item renders like this: https://ibb.co/kS2NkBD

for reference, it is meant to look like this: https://ibb.co/Kqw7hJj

i am using version 5.9.1 of geckolib, the latest at the time written

(note: i changed the UV from box to per-face UV, does that change anything?)
