My item app got rejected because Envato says it's a copy

I uploaded my app to Codecanyon and after a few days I got this message. The fact that my app doesn’t copy with other apps, which makes me confused. Before uploading to Codecanyon, I uploaded this app to Appstore and I got reject for the first time. Is it possible that the app was rejected at Codecanyon because it was uploaded to the App Store, even it haven’t been available yet? Or is it because of the app theme?
