You already have been given the answer to your problem, so there is no remaining puzzle. -summarize- is summarizing the values underneath the value labels. Which version do you wish to -summarize-? If the value labels are the real values, you need to -decode- that variable and then convert it to numeric with -destring- or -real()-.
