qBittorrent official forums

Hi all, I've been using qBittorrent for a while now and I think it's great.
I am having trouble understanding how torrents work now due to a bunch of torrents I am currently trying to download. I have searched google and even these forums to try and better understand before I posted this but I'm sorry if I somehow missed the answers.

Generally I assumed that if I was connected to seeds that I would download the pieces I am missing and that the number outside of the parenthesis is the number of users I'm actually connected to.
I've had qbittorrent open non-stop for several days and all of these torrents have stalled despite being connected to seeds. For example, this one torrent I have been stuck at 95.4% for a couple of days even though the whole time it has said I have been connected to at least a couple of seeds. Right now it says "5(6)" for seeds yet nothing is happening.

These are older torrents, so I can understand the low count of seeds and peers, and newer torrents still work fine for me. I'm just wondering why these ones aren't.

Either the seeds are "fake" and trying to poison the torrent, or it's yet another qBitTorrent bug.

Try qBT v3.3.16 and/or v4.0.4 and see if that helps.
...If not, it could be a bug in qBT or libtorrent.
