Hi,
It’s a little hard to tell how your door pivot is setup for its location based on the front view from Blender. If it’s on the edge this would be the ideal place so that it’s rotating accordingly. If that is the case when you place the mesh in the Blueprint you’ll want to make sure that it’s lined up with the world origin of the component because this will be the pivot point of your BP and not your meshes pivot.
Thank you!
