FS2002 KDCA LANDING PROBLEM

I have a problem with the AI landing at KDCA in FS2002.
The AI land on the longest runway (01) but land long..300ft down the runway . Because of this they roll off the end of the runway into the river/grass.
Is there anyway to adjust the runway in AFCAD to have the AI land "on the numbers"?? There is no threshold for the runway.
Thanks.
