1.32 BETA and older versions act odd with two thepiratebay.org trackers:

http://tracker.thepiratebay.org/announce
udp://tracker.thepiratebay.org:80/announce

These trackers are automatically unchecked:

Even if those trackers are manually checked to be included, those trackers still aren't included and are lost after Update torrent:

I understand that these trackers aren't alive at the moment, but such behavior is still bad because:

1. It's odd to exclude some particular trackers (even if those trackers aren't alive) and leave checked some other trackers that are dead too.
2. User manually chooses to include these trackers, but those trackers aren't included and no prompt is given.
3. openbittorrent.com and demonoid trackers were dead for a while, but resurrected. The same might happen with any other tracker, including thepiratebay.org too.

I wonder why this issue happened.

Is it something unique to these 2 thepiratebay.org trackers or are there more unsupported trackers like these 2?

Here's the link to a sample .torrent file which has thepiratebay.org tracker:
