It's easiest to see with spheres, but it also happens with boxes and cylinders. In an empty world, if you add multiple spheres to the same snap location on the grid, they will stack on top of each other (a bit unrealistically). Then if you insert another sphere that partially overlaps the bottom sphere, the spheres on the ground will snap apart, so that the upper spheres go from being improbably balanced to floating unsupported (see screenshots).

If you right click and delete one of the spheres on the ground, everything wakes up and falls (like Wile E Coyote looking down).

I'm guessing that the upper spheres are auto-disabled and should be re-enabled when something comes in contact with the support sphere on the ground.
