Niagara system using chaos break events affects all objects in the world, help please!

I am using a niagara system to add an effect to a breaking flowerpot. The system uses “Spawn from chaos” and is set to use chaos break events, and it works fine except that it affects ALL breaking events in the world, not just flowerpots.

I noticed I could put a specific chaos solver in the niagara system so I figured I could create a chaos solver and drag it into my scene and then set my flowerpots to use that solver, and set the niagara system to respond only to events from that solver.

Problem is the flowerpots fall through surfaces when I select to use my custom solver. Any help would be appreciated!
