New VM alert keeps alerting on already existing VMs

Hey all,

I have this alert setup to send emails when a new VM has been created.

It works great.
The last few weeks I've been having issues where it will send alerts on VMs that aren't new.

Specifically there's two hosts that it seems to be picking from when this happens. I went ahead and removed them from our node lists and re-added them.

Is there maybe anything else that would cause this alert to keep triggering on old VMs?
