Hello:
Yes it can be an issue.
Since you can rewrite the articles just do some changes in the article to make it unique.
Try changing the article to how you would write the article. It is quite simple to redo it and doesn't take too much time.
If you want there are some article spinners out there that can do the rewriting for you but they can also be a bit messy in language if you are not careful.
Sincerely,
Bryan
