some "Encountered two children with the same key" warnings reported by Chrome console

[ChampionRoy]

My code and config like this: 1.place sAlert component in my main app component: <Alert stack={{limit: 3, spacing: 50}} effect='slide' position='top-right' timeout={5000} offset={50} /> 2.and make calls to activate alerts Alert.error('some error message'); When I triple clicked a button and get an invalid form ,then make three calls on activate alerts. After alerts fade away, some warnings report on Chrome console: Anyone has same problems?

+1 same applies to me

Warning: Encountered two children with the same key,alert-key-xnlhe6qvdwr-undefined. Keys should be unique so that components maintain their identity across updates. Non-unique keys may cause children to be duplicated and/or omitted — the behavior is unsupported and could change in a future version.
