Strange (announce?) behavior


In these days I got some Hit n Runs on a tracker. But there is a very strange behavior:

In rutorrent some torrents appear to have been properly and completely downloaded, and are shown correctly in seeding . However in the tracker, them appear as if they were not seeding. Also the download amount is absurd: for example, a 10GB file appears to have a download amount of 200GB.

Now I would understand if this strange behavior is influenced by rtorrent settings (or more, in short, that it is caused by my end) or are tracker’s problem.
