Skeletal mesh not appearing in reference pose

I’ve imported a mesh with a skeleton from Blender (exported as fbx) and then changed the pose in the skeletal mesh editor. The mesh appears in the correct pose within the skeletal mesh window in the Unreal Editor, but if I put the object into a scene or make a blueprint from it then this pose isn’t used.

Is there some way of forcing the blueprint to use the mesh in the reference pose?
