It's just weird cause I only haver one torrent uploading at 14kbs…but I have torrents which, at least had, a lot of leechers.
You may have a pot forwarding issue with your network. You need to be sure that the port that your torrent client uses is forwarded through your home network (router) or VPN to your computer, both in TCP and UDP. This is a critical step, necessary for getting proper upload traffic.
