Duplicating emitter asset leads to cross communication between modules

Copying an emitter asset through the content browser will lead to cross communication when the two are used in the same system 

1. Create a new emitter asset, choosing "Copy from existing emitter", select fountain as the emitter to copy
2. In the content browser copy and paste the new emitter using ctrl+c and ctrl+v
3. Open the newly copied emitter and change the particle color
4. Create a Niagara system from the two emitters
5. Disable the spawn rate module on the emitter that was copied from the original

RESULT

Both emitters will stop spawning particles. Note: this does not happen if you create the second emitter in the same way the first one ("Copy from existing emitter")
