You've only had that torrent for less than a day, just be patient. There are 26 possible seeders and only 3 leechers, so your odds of seeding data to anyone is just lower than if it were the other way around. If you still haven't seeded anything at all from it after a couple weeks, then there might actually be a problem.
If you want to fix your ratio, just seed back the other things you've downloaded like Grenadier or the various manga. You've seeded a teeny bit of 3 things according to your tracker profile (so you shouldn't have a connection problem), but the only way to fix your ratio is to just wait for things to seed back. Most of the things you've downloaded have a lot of seeds, so it might take a while to creep back up. Watch what you snagged while you wait.
