@yepyep7891 intriguing, at least. could you provide a screenshot of your tracker tab for one of the cases? don't forget to hide your passkey tho.

Here's an example, in my case it's a legitimately unregistered torrent, which do not report peers/seeds data. If your torrrent status says working and the message says unregistered torrent, that's a mystery to me. I would suspect that there would be more than one tracker, but guess you'd have mentioned if that was the case.
Did you notice if all the torrents with this "warning" tracker status share the same domain?
