Add Event Grid subscription function button uses wrong event type.

I'm attempting to create a new Event Grid Subscription after deploying an EventGridTrigger function using the "Add Event Grid subscription" link in the function. When I specify my Event Type that I want to target and hit save, it ignores it while creating the Sub and instead populates Microsoft.EventHub.CaptureFileCreated as the event. This seems like a bug to me because then I have to go in and re-add my Event that I added in the dialog the first time.
