SHM Custom sending Push Notifications when Notifications not selected

I created a Custom SHM to beep when the doors are opened. I just have Audio Notifications enabled to play a track on the Aeon Doorbell. Finally got this working but everytime it executes, it sends a Push notification to both me and my wife.
I deleted that Custom App and it stopped, but when I re-created it, it started again. What gives?

Anyone got any ideas why this is happening or how I can fix it?

Same issue here, could you resolve in the meantime?
