Niagara system particle compoenent event "On System Finished" won't trigger

Here’s my setup :

And inside the niagara system :

I tried to set the inactive response parameter of the system node to “kill” or “Complete” but neither worked, same for every emitter node. Even tried to set the life cycle mode parameter of emitter nodes to System while having the system node inactive response set on “kill” and none of those worked.

If someone have any ideas on the issue, it would be greatly appreciated, thanks !
