Summary
the invisible Smart Object Subsystem Rendering Actor actor gets created in any maps you load and gets selected on accident when you do lasso selects in the top down viewport, thus causing problems when you try to frame the viewport on the selected items or group the sel items or export the sel items to blueprint or level instance because this invisible thing is also part of your selection against your will and there’s nothing you can do to get rid of it. you can’t delete it. you can hide it, but it’s a bit tricky to select it and hide it because you’ll be selecting the skySphere as well. and hiding isn’t a real solution either because whenever you hide other stuff and unhide that, this will be unhidden as well and you’ll have to go through the tricky process of hiding it all over again. etc etc.

Steps to Reproduce
if you do a lasso select in the top down viewport, you’ll select an invisible Smart Object Subsystem Rendering Actor actor most of the most of the time accidentally as it has a very large bounding box.
Expected Result
it shouldn’t be selectable as it’s not an editable part of a level like a staticMesh or light.
Observed Result
it gets selected anyways and thus causes issues as you’re trying to edit your level or group objects or convert your selection into a blueprint or levelInstance because it’s selected too but the user doesn’t know because it’s invisible.
