Issues editing a duplicated frame

I am building a wire frame - In the spirit of iteration, I duplicated my first frame, and would like to now rearrange images and text in this new second frame. However, whenever I attempt to move something, it merely duplicates another box or text file, and then I am unable to delete the originals. I’m super confused as to why this is. Any recommendations?

If you are holding option when you drag items it will duplicate.

If you have changed your first frame into a component (if it’s purple in the layer list) then you will not be able to iterate freely.
