It appears that you are in Play in Editor (PIE) mode. Those objects are being displayed for Edit Mode only. It is expected that they are not visible during play. If you hit ESC those assets will be visible again.
Ok maybe some kind of note on items like that to reflect that would help. Even a word between brackets or something such as “Displayed in Edit Mode Only”. Because I thought it would display a default sprite of some kind and a light would be shown while playing.
