Its hard to answer your question without more information. What version of Photoshop are you using? What version of Contact sheet? Did you have Contact sheet flatten the documents or leave them layered. Do you want to replace deleted images or leave the areas empty? If you want the Images to be re-arranged the best thing to do is move the image you don't want in the contact sheets form the source folders and regenerate the contact sheets.
