WPTouch show draft posts and deleted posts

I have activated the WPtouch in my website, but there are some pre-installed posts from my theme that show up in mobile view. Even I deleted these post, they still appear. my website: http://www.nexthk.com

Is there any way to delete them? The fact is that I cannot even see these posts in my wordpress admin. It works weird now. Please help.
