Urdf spawn error

Hi i tried isaacgymEnvs example and legged_gym with my custom quadruped robot
but my robot spawned like that

but it spawned well in gazebo and the environment that i created like below
( i made below environment using cartpole example)

then, I think i have to test inversely
i get anymal robot urdf from isaacGymEnv and tested in my environment

what is the problem?
you can download my urdf file in my git repo
