Looked at your account metadata. You have 32 files and 6 folders in the Archive. Those 6 folders contains 18 files. Folders in the Archive are "flat" meaning you cannot see inside of them so will need to Restore them to see their contents.
If you are the owner of a shared folder then if a non-owner removes items they go into your Archive and also into the Trash (on Mac OS X) or Recycle Bin (on Windows).
