Why a light in a hidden blueprint is visible?

I have a blueprint that has 3 static meshes and a spot light (movable) as components. When the game starts the blueprint has the property “Actor is hidden in game” enabled and it works… but it only works for the three static meshes. The light coming out of the spotlight is lighting me scene, even though the blueprint that contains it is hidden?

Am I doing something wrong, or is it something else that I need to do?
