Importing Animation from Blender make animation scale smaller

I’m Having a problem , when i importing animation using fbx , the animation keep become small , the skeleton itself is at normal size. the size itself can be fixed with enabling root animation , but the movement scale didnt fixed

okay i just found my problem ,
its actually the armature that i use , when i change the name for that armature to something else my animation now have correct size . in my case , that “Bone1” used to be named armature
