Having some issues moving bones

I am working on a swept wing aircraft. When I export from blender into UE4, I can open skeletal mesh and rotate the bones just fine. They are all working. (Flight Control Surfaces)

But when I make the blueprint, and using poseable mesh, if I try to rotate x° it changes all 3 axis’.

They are all at 0° in blender but if I check the rest rotations in UE4 using get bone rotation, they are all weird rotations.

But, like I said, In the visual physics tab in UE4, I can move them properly.

Edit: It is set to Component space.
