Catch torrent URLs with custom regular expressions not working

[Latonki]

I'm trying to create regular expressions so that Torrent Control will only catch the torrent URLs from specific trackers. I was able to create a regular expression and I ticked catch torrent URLs before inputting my regular expression into the textbox but the issue was that after I clicked save, closed the addon page, and then reopen the addon page, the regular expression disappeared.
