I need to undo an Control Group of 9 Objects

I followed the previous discussion regarding control groups but so far the suggestions have not helped. I am on page 5 of a project that self-created the control group. I have been using CD for decades and have not had this issue come up before. The last post mentioned selecting a drop shadow but I did not insert one. I created a drop shadow using the same text and grouped them but I cannot select anything in the control group to delete it or break it apart. I supposed i could trace the artwork but I would rather find an easier and quicker solutions. Anyone have any ideas?
