How to reset viewport in blueprint after simulation?

Good day, if I run a simulation in a blueprint viewport and my ChildActor spawns a class in it, then when I try to do another simulation the previous simulation spawned actors still persist, until I close and reopen the blueprint again. Is there a way to reset or clean the previous simulation in a constructor or otherwise? Thanks

Well its little bit brute force but I add this function to Event Begin of the same character, its only works if you not placing too many types of actors to your blueprint and quite messy(will delete all actors if you forgot Debug on true)…
