I-94 error

on my mother I-94 there is an error,she entered US on Sep 2003,and is permitted to stay for 6 months till March 2004,but it is written March 2003 instead 2004(of course there is also the addmission date which is sep 2003)..this error is nonsense because it is logically refused,but may this cause for my mother a problem later,and what should be done at port od departure?thanks

contact the neasert BCIS office, call them and ask for the correction.
