Thanks for the reply.
So that means that everything (literally everything) is going through the proxy?
I have enabled "Use proxy to resolve names" (ipleak was showing my real address if it wasn't enabled) but I'm afraid there might be something that could potentially leak my real address because some torrents are being downloaded very quickly (around >1.5MB/s) and I don't think that's possible if you're using Tor as proxy. I mean, tor's average download speed is <5Mb/s (<625kB/s) , so there might be something wrong going on there.
So far I have done this:
Networks > Connections:
Outgoing Peer Connection Encryption (Encrypted Only)
Incoming Peer Connection Encryption (Encrypted Only)
Outoing Peer Connection Protocol (TCP Only)
Incoming Peer Connection Protocol (TCP Only)
Network > Proxy:
Use proxy to resolve names
DHT:
Startup DHT Mode: (Off)
DHT mode for normal transfers: (Off)
