No, it has absolutely nothing whatsoever to do with your client. As Al_Sleeper ought to know. And downgrading didn't actually make any difference - getting decent speeds on a torrent sporadically is normal, and occurs whenever you get a request to upload a particular piece. The version of utorrent you're using makes no difference to that.
You ought to take another look at your screenshot and use your brain a bit. Maybe have a read through this subforum, where this exact same question has been answered thousands of times.
But just to make it clear - the number of peers is irrelevant. What is important is the ratio of seeders to peers. And, as you can see in your screenshot, that second Code Geass torrent - to use your example - has a ratio of over 11 to 1. Or, to put it another way, for every one person downloading, there are eleven other people trying to upload data to them. So obviously it's going to be tough for you to upload a torrent at anywhere near a decent speed, because there are so many other people doing it instead that it's hard to get an opportunity to send anything. Downloaders only have so much bandwidth available, after all.
This is very common with BakaBT torrents - the overall seed:peer ratio for the site is something like 20:1 - and has been discussed many, many times in this subforum. I can see several topics on it on the first page alone. There is also a lot of excellent advice on how to improve your ratio, so have a read through. It'll answer all your questions.
