% Complete - Moved from one Schedule sheet to Another Schedule.

I been creating a master schedule to keep up with all my projects. When I selected the row I wanted to move to anther sheet. it transfers over correctly. Now my question is. Why does my % Complete not work. Please see below the picture as well. Were the blue is highlighted i would like that to show the completion %. It works when i create a new project but for some reason it does not work when i transfer to another sheet.
