Actors that are created via a child actor component should not be selectable as entries for an actor property.
Create an Actor Blueprint
Add an Actor variable and make it public
Add a Child Actor Component and set the class to something valid
Compile and place an instance of the blueprint actor in the world
Go to the property details and use the drop down for the actor variable to pick the Child Actor.
Expected: The Child Actor should not be listed in the drop down.
