FASTEXPORT MLSCRIPT Getting junk values like p1

Hi,
While exporting data from Teradata table with MLSCRIPT option to generate mload script too. I am getting below strings p1<96> or p1 instead of DATE/TIME/TIMESTAMP fields in layout section.
.....
p1<96>.FIELD COLUMN1 * DATE;
p1<96>p1<96>.FIELD COLUMN2 * CHAR(1);
.......
Could some one help me in understanding this, why it is generating like this for DATE/TIMESTAMPE/TIME fields alone? Is this string gets change  like p1<96> , p1, p1<65>,... for defferent date/timestamp fields?
Thanks,
Bala Chuppala
