If they appear in your LW Library window under shared then that means they're being shared. LW is designed so we can't find our own shared files in our searches.

To find out if they've been found in other people's searches or uplded to others, go to LW Library window & click on the shared folder they're in. The files should appear as you mentioned. Now look to the far right of the window & look under the Uplds & Hits columns which will tell you if others have seen your files.
