In my profile I can see that I've cast 2 downvotes.
But I am relatively sure that I've only downvoted one answer and I only see one entry in the "votes" category of my profile.
Is it possible that the summary is wrong?
Here is an image of my reputation history: http://i.stack.imgur.com/xF0Rz.png
As you can see there, I have only one "downvoted" event in my entire history, and the "show removed posts" checkbox is enabled.
There is also only one downvote in my "votes"-list
