Box Shapes when I Move Them

When I right click and move my items around the screen they turn into box shapes? Is there a way to get them back to looking as they should? Did I click something that I shouldn’t have? I am a relatively new user and any help would be greatly appreciated.

You must have enabled Dynamic Display in your rendered mode. It is in the Display panel, or in menu under Options -> View… specific display mode. There, under Objects.
