I fixed mine. It was a bit of a pain but there was a loop causing it.
I manually edited the mysql database and took out the entry to the torrent file. This fixed it, but when I refreshed the page, it came back again. So the way I finally got it to remove was by temporarily turning OFF the page refresh in torrentflux.
Then editing it out of the torrentflux mysql database, then removing the name_of_your_torrent.stat AND name_of_your_torrent.torrent file.
Once I did this it has been gone forever
Sorry I found this a couple of days ago and didn't have time to update this.
If you need a hand doing it let me know.
