I have a problem with the resized dino saddle, please help

I resized the rex to 30% of original size, but for the first time i can tame it and put a saddle on it, later after done some other mod, i can’t put saddle on it anymore, i think i changed some of the values, but i don’t recall anything affects the saddle, anyone has a clue?

If you changed any of the name tags aside from "descriptive name, then that will cause problems with the saddle.
