Sounds like you are looking at the incoming searches part of the monitor pane, not the uploads. No worries.

That part just shows all the search terms flowing by/through your computer. If one of the terms matches one of your shared files, it will be recorded as a "hit," or maybe even as an upload.

Play around with dragging the two parts of the monitor pane to see what I mean. You have to click the "show incoming searches" checkbox to see those though.
