On the following screenshot all the torrents, starting with "Shadowhunters Season 1" are 100% downloaded. And yet, as you can see, Deluge displays them as "Paused 0% (zero)", no download speed and no seeds. I had added over 50 torrents and only after I removed the ones from the screenshot, the interface began showing percents, download speed and seeds.
