ADDING FEATURES TO REPORT AFTER PROGRAM IS RUN

ADDING FEATURES TO REPORT AFTER PROGRAM IS RUN

I have run the program. I now need to add a dimension I forgot. 
I don't understand why when I need to add a dimension to a report, pull up Teach Mode, add the dimension, and regenerate the report, the dimension generates at the very bottom of the report instead of where I have created the dimension in the program, 

Why doesn't it generate the dimension exactly in the report as where I created it in the Program?
