Default Mannequins causing big frame drop?

Hey everyone. got an interesting issue. I have a completely blank level for my lobby since it’s all Widget. Inside of my level is 4 character actor previews so the player can see what the character looks like on selection. At the moment, until my final characters are finished, I’m just using 4 basic mannequins with 4 different colors. When I drop in these 4 actors into the level, my framerate goes from 90fps to 10fps. even my fully populated map gives me at least 60fps. I have nothing special and zero blueprints with these actors. Just a mannequin, and a 2d scene capture component. That’s it. Any ideas?
