Copy part of trasformed layer

Hi all,
I'm new to AI and need a bit of help please... I have made a label for a certain packaging (1lbs) and somehow duplicated it to print 8 copies on one A4 page. I can't remember but I think I used transform. Now, some months later, I wish to make the label slightly bigger for a bigger (2lbs) packaging. When I copy & paste the text artwork to a new document, I get 8 copies and I only want one. I hope this makes sense!?  Any advice will be very much appreciated thanks!

Johan
