Voice memos do not delete (1 hr of recordings)!

Where I find these "undeleted" voice memos. When I connect iPhone, itunes opens and on the top right I click iPhone. There are 10 tabs in total (Summary - Info - Apps - Tones - Music - Movies - TV Shows - Books - Photos - On This iPhone). I click On This iPhone. On the far left side, it lists from top to bottom Music - Movies - Tones - All of my playlists. The last one lists Voice Memo. I click on Voice Memo. I find 10 messages from June and July 2012, which I have deleted off of my iphone AND itunes. I want to delete these 10 voice memos. They are NOT on iPhone or iTunes. I tried searching through computer, but nothing is found.

So why not delete them now? I physically can't. I right click on the voice memo and there is no option to Copy, Paste, DELETE file. It only gives the option of playing the music. It is easier to see what I am saying so I am attaching a snapshot. Notice that the voice memos are on my iphone, but not in itunes. I looked all over itunes and there is not one voice memo. Also, under the Music tab, include voice memos is not checked.
