Why there are duplicate actors in world outliner?

Are they just fixed in your blueprint, or are you adding them with code?

Hi, I have an actor with 8 child actors, but in the world outliner there are 12. Half of the child actors duplicate and I can’t select to delete them. Problem is when I cast to these actors, sometimes it casts to the duplicates. This is not an online game and I didn’t select “replicate” on them. Can someone help me ? Thankyou very much.

They are fixed, I only cast to them to change some variables at play.

I placed the actor again in the scene and it was working fine, but it seems when I start the project again, the duplicates appear again.
