New UActorComponents get instantiated On Play.

In my scene, I have some UActorComponents that are instantiated already that have their properties edited and set. These are the Actor Components that I would like to use for my purposes. However, when I press play in the editor, NEW actor components get instantiated for seemingly no apparent reason. These properties have not been edited and set and I do not want to use these but sometimes they are referred to even though I choose the ones in the scene that I would like to use. Is this intended behavior from the engine?
