Can't add component in editing time?

I want to replace InstancedStaticMeshComponent to HierarchicalInstancedStaticMeshComponent in editing time and save level with that.
But it’s not appear in detail panel.

I’m try this blueprint minimum version.
Parent class is ‘Actor Action Utility’.

This blueprint can create actor but can’t see component in detail panel and it didn’t save in level.
I tested with ‘GetComponentByClass’. It printed components in my actor.

So i think it is problem only in ‘Actor Action Utility’? answer is NO
I tryed with actor blueprint but can’t see too.

How can i replace component in editing time with blueprint script.

sorry for my bad english hehe…
