I'm getting something similar. I am currently downloading nothing, and seeding about 10 torrents, but still have the red arrow with a "1" next to it. I haven't downloaded a new torrent for about a week now, and I've logged on & off about a dozen times, but it still shows one torrent downloading. Sometimes the seeding & downloading are expressed in multiples, like I'm seeding 4 times as many torrents and downloading 4. A bit strange, but it doesn't exactly bother me.
