Notice that in the error window one line is pink and one line is red. Both are errors, the one that is selected turns pink, the first one being the default when the window opens. If you click on the red line, it will turn pick and the other will revert to red. When you click on the more button, it tells you more about the selected (pink) error. So now you have to run it again, and when the error occurs, check out the "more" details for both errors.
