If I have provided two answers to the same question, there is only one answer shown in my user profile. This answer is followed by "(2)", indicating that two answers are there, and the rep shown is the sum of those two answers' rep. Clicking on this takes you to the highest-rated (or maybe the oldest?) of the two answers.
This is misleading if you are looking at how much rep you got for a given answer because you want to know how close you are to a badge. It also makes it hard to get to the second answer that was provided.
