bugs in the kit

Hi,
I bought an Arduino Starter kit, the book shows the project 05 at page 64 where, according to the figure, the potentiometer should occupy a very small place but it's so big that it's impossible to fit as shown, it's twice as big. As it is a kit for beginners, you could have add an errata corrige for the book, in the case the pieces were changed. I also have the colors of the servo that are mixed...how a beginner is supposed to modify a connector?
