Yo-kai watch Model ripping project

[soantyphalt]

I downloaded the Yo-Kai watch models and tried playing around with them on unity. I noticed the jibanyan model doesn't seem to loop its animation properly and the walk/run animation looks jittery. Any idea why this is the case? I assume in the original game it ran smoothly. Anybody know what I did wrong? Idk tho, as I am not really in the field. Would be grateful for a response.
The model number of the jibanyan I am talking about is Y152000 and the animation is named y152000_p10_02501d_rnl.
