I see, yes - if you apply to a group, the EventSource will apply to each device in that group, which is why you're getting duplicate alerts. You'll need to make sure the EventSource only applies to one device to avoid the duplicates - a few ideas on which device to apply to are: a billing device if you have one in monitoring (as that is unlikely to come & go), you can add 'status.aws.amazon.com' as a device and apply it to that, or you can just pick any non-temporary device in your AWS Device Group. Does that make sense?
