Back on track: I see 65 torrents seeding in States, matching the Trackers section with 65 torrents split in 4 different trackers, all fine.
Back to your question, it's unclear what you want to accomplish. Do you mean adding under Trackers more torrents to for example the tracker "iptorrents.com"?
If this is your request it's not possible, not because of Deluge but well because it's not how BitTorrent works.
Let's take 2 tracker websites:
a.com
b.com
If you take 1 torrent from each site, you will have 2 torrents under States and the below result under Trackers:
a.com(1)
b.com(1)
You can only share torrents with the community of its site. You cannot "regroup", torrents from a.com are not registered on b.com and vice versa.
If you want to add more torrent for a particular tracker, you need to download only from this website.
