Ahhh, you're enjoying the loveliness that caused DAZ to switch to the Bullet Physics engine. One of the maddening things of the C7 and earlier physics was the sometimes funny, but usually just annoying, trait of items barely touching each other and then exploding out of the scene.

It looks like you've got everything working correctly. Now it's just a matter of adjusting - and this might take a little while in C7. First Recreate the replicator group but this time, dial down the "bounce" of the source object to 1-5% and see how that treats you.
