Cascade particle emitter not being destroyed with Actor

I am spawning a Cascade Particle System of some flames, in Blueprints via the Spawn Emitter at Location node. The thing is that as soon as I delete the Actor that spawns the emitter by deleting it from the Outliner the Emitter remains. I thought it might have spawned as a new Actor or something but I could not find anything in the Outliner and the number of Actors also stayed the same. Am I missing a setting or something? How can something be in the world without it being an Actor or a component of an Actor? I also tried selecting it to try and move it but to no avail.

Thanks in advance!
