When i disable the setting bittorrent -> torrent queuing i get over 20 active torrents that are seeding.
This doesn’t answer your main question but maybe just leave it as-is and don’t overthink it? I find that torrent clients work best with torrent queuing disabled & letting the torrent client handle everything. Your torrent client is going to do the best it can with the available bandwidth/connections it can use - Definitely feel free to configure those if you want to control that a bit (“Global Maximum Number of Connections” and “Global Rate Limits”).
Also remember it’s not just dependent on your own limits, each peer connecting to you has their own bandwidth/connection limits.
