Can't spawn static meshes within a volume?

Hey all, I made a BP that’s supposed to spawn some trash models within the constraints of a volume. I had previously used this same system to spawn physics objects, which works fine, but when I swap out physics actors for plain old static meshes, nothing seems to spawn.

I’ve also noticed that the objects do show up in the viewport, but not in-game, and if I resize the Volume box in the viewport, everything still spawns in the same little area.
