Ideally unity prefabs should be recreated at unreal side as blueprints.
Unity is currently (2018.3...2019.1) rolling out nested prefab support, so at a basic level the exporter should be acting in the way compatible to previous unity releases where only non-nested prefabs were supported.
Nested support - if possible - will have to be delayed for later.
