InDesign is creating a problem wherein I finish an entire document and it still says there is overset text. When I create a new frame to put it into to see what it is, I find that InDesign has duplicated the text of the entire document. When I try to delete the extra, it just copies the text over and over and puts it right back, including if I try to delete the frame that the extra text is inside of. How do I make this stop?
