TriggerBox BP not casting ActorObject BP

I’m having a problem which I find quite strange, I can’t command a Trigger BP to do something, like destroying/Set Actor Location, unless I do an ActorBP reference, and allow to be editable, then I insert the actor instance from the level into the details-default, however, I need to do that without having to do such thing.

It turns out that it doesn’t want to cass unless I do what I stated above, why such thing happens? I’ve saw Matthew Waldstein video using UMG and the variables are not set to be editable.

Found the solution after I decided to take a more detailed look in Wadstein video, it happens that instances put on the level won’t work, instead you have to use the Spawn Actor from Class
