Nagging problem

Nonexistent runways that come with afcads. Like my JFK afcad, the ATIS says "landing and departing runway 2, runway 3, runway 4, runway 5, runway 6, runway 7, runway 8, runway 9, runway 10, runway 11, runway 12, runway 13, runway 13L and runway 13 R." Of course, the only real runways at JFK are the usual 4. On my San Juan AFCAD there's nonexistent runways 4/22 and 5/23.
Is there any real purpose to these? How could a designer have possibly messed up that bad, I figure there's got to be a use for them somehow. It's extremely annoying, and I don't see what purpose it serves.
Which brings me to another problem-when I tried to view the afcad, by hitting "open airport," the program freezes as it says "collecting airports..." Will updating afcad solve this?
