Hubitat / Noonlight app - triggering Noonlight twice

I'm using the Noonlight integration y'all built - which is much appreciated! However, it is sending two "siren" events to Noonlight, which means Noonlight gets two separate alarm events. I'll get two calls from them back to back, which means I can't answer the second one - and causes confusion with their dispatchers. 

Any ideas what might be causing that? It looks like HSM is sending the "intrusion" twice.
