Odd issue with My Documents and Documents library

Today, I was looking for an Excel file and encountered the following issue:

If I go to Libraries\Documents\Property Files\1105 Dart, I can't see the file I need. However, I can see it if I go to
C:\Users\Sales\Documents\Property Files\1105 Dart



I have 156 files in "Documents" and 153 files in "My Documents". Any idea how to correct this? My documents may have gotten 'out of control' after I started using Bit Torrent Sync to sync the documents folder between my desktop and laptop.

Thanks for your help!

The actual view is:
Libraries\Documents\files --> are from 2 Location; example = 22 files

Libraries\Documents\My Document (user;Sales) --> actual location -> C:\Users\Sales\Documents; example =17 files

Libraries\Documents\Public Document --> actual location --> C:\Users\Public\Documents; example = 5 files.

Both location 17 + 5 = 22 files.

If you delete any of the files in Libraries\Documents\files --> it also delete the same file, depend the actual location.

But if another user log in (say, Eric); then the number of files depend on the user, Eric.
If user, Eric, at C:\Users\Eric\My Documents have 28 files.

Then the Libraries\Documents\files will be 28 (user, Eric) + 5 (Public) = 33 files.
