Duplicative content isn't exactly the same as copyright strikes or Content ID claims. We’re only allowing channels into YPP if their content is original & adds value. You can read more here: http://goo.gl/1n7ZVS . Also, you can re-apply to YPP within 30 days.
While we can't go into specifics. The best thing you can do is keep uploading original content as the more info/content for us to review, the better and you should receive a second update in the near future!
