@citydwelleer-0 there is no cap on seeding, you just don't know how torrent works.
If a torrent contains multiple files, and you only download a few, you will never become a seeder. If you keep that torrent active in your client after you have finished downloading, it will stay using one of your download slots indefinitely, and you only have 15.
To help visualize, imagine "progress" as a value ranging from 0 to 1. If you download all files, progress is 1. If you leave any file unchecked, progress will always be less than 1. You only become a seeder when progress reaches 1.
So when you finish downloading, the client reports "seeding" because you have finished downloading, and you are able to seed the files you now have, but since you don't have ALL files, you are still leeching to the tracker.
To avoid this, when you don't intend to download 100% of a torrent's content, you have to pause or remove it from your client as soon as you finish downloading. Otherwise it will stay consuming 1 download slot.
The reason why pausing did not immediately released those download slots, is because it can take from 30 minutes to 1 hour for the tracker to update.
