Bone axis/rotation problems (from blender to UE4)

so i went back in blender to check de axis from my bones and meshes, and as far as i can see the axis’s for the bones and meshes are there perfectly in place (as it should be, because of using the “shift+s” methode) (image 5A & 5B):

i have searched a lot on the internet and watched a hell of a lot of tutorials for it but unfortunately i can’t find the solution for this problem… :expressionless:
and i really running out of options here… :frowning:

I’m using: windows 7, blender 2.80 & unreal editor 4.20.3
here i have a download link to this pictures, blender file & the fbx file: https://we.tl/t-0vUF3JDmJz

so if you know a solution, please tell me! ;D
really big thanks already for reading and thinking! :wink:
