I don't know what can cause this bug..

I have some suspicions about what is going wrong.

How recent is this version ?

The files you deselected are they deleted ? Or is some of the data still on disk and being used to seed it ?

The version is 2.1dev but i can't tell you which partical svn is this.The situation is next:
There is a torrent with 5 files.First I downloaded 1 from the files, then I started to download another file and this is the result:)

Can you try upgrading to the latest, I thought I had fixed all bugs related to these things, so if you can reproduce it with the latest, we can be sure that there are some bugs left.

Very good Geogre you fixed it Please look at the screenshot again and see.. what is in downloaded and size.. 1gb dowloaded 700 mb size.The sutiation is the same.
