question about 'Front Lines' DVD package

would like to know if anybodys copy of disney treasures-on the front lines has the same anomaly as mine. Although I know that this set was released in may,2004, my copy has NO date on either the back label or the booklet or along the edge of the discs themselves. Does anybodys else copy ALSO lack a date? Would just like to find this out. Thanks.
