Actor appears hidden in editor viewport until moved to different sublevel

User's blueprints disappear from level during editing with no warnings, errors, messages, or additional information. They return to visible if they are moved into a new sublevel and appear during PIE without any errors. The assets are set to visible (true), hidden in game (false), and set to visible in the world outliner.

According to the user, this has been occurring since 4.5.

1. Download, unzip, open attached project

results

Editor opens. The level viewport shows a floor with two lights and a player start. World outliner shows Sliding_Door_67 blueprint in level and it can be selected, but is not rendered.

Expected

Door should be visible in level viewport.
