Pardex's dashboard

Hi, I'm new using Twitter.
I don't know why but I'm having some problems in my Twitter.
First, my following/follower counter is wrong. I have 3 following and I should have 3 followers too. I recieve a mail that with that message: "XXX is now following you on Twitter", But i see the counter and I don't have followers.

The second, when I want unfollow somebody, I can't. I press the unfollow button and I go to my profile and I can see the same guy in my following counter.

Please help me.
Thanks a lot.
