WP handles PIE Editor only properly (doesn't load the actors at all) but the old level streaming system just hides them through the FPrimitiveSceneProxy. So in this instance, the bug is that the LevelInstance sub actors don't get their primitives flagged properly so that they get hidden in PIE.
More details and repro project can be found in the UDN link.
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-183243 in the post.
