How do I use the "No Save" behavior properly?

So, here's what's going on currently.

I have enemies that start a game with 100 health on a layout, when their health reaches 0 (after being hit by the player) they then destroy themselves and drop a random item.

If you load a game and return to the layout, the enemies that are killed return briefly, then die and drop an item (because the game knows to destroy them, because their health should be 0).

They all have the "No Save" behavior, but still seem to be saving.

I would just like all of the enemies to return to the layout when the save is loaded.

Any idea why the "No Save" wouldn't work in this situation, or does anyone have a better way to cause the enemies to reload properly?

thanks!
