After you go to the pose preset options panel are you selecting save all (meaning all morphs and translations) or custom? If you select custom then in the drop down on the right (the little arrow) and select "select all translations" it should save the pose properly. If you do a character from morphs you would select all morphs instead. One thing to keep in mind when you save poses is that you should try and the character by the body but by the hip so that next time the pose will pop the character back onto the zero location.
