[UE5] Prefab Component not working

Hi there,

when I'm using the prefab component within a BP the Prefabasset is not shown.
I have attachted the prefab component to a scene component.
The "P" Sprite and the green boundaries are shown correctly, only the prefab asset itself is not displayed.

Any hints what could be the problem here?
I'm using UE 5.0.3-20979098
