Logos

Im starting a new save and would like to to add all Logos,End zones, Jersey etc ..from my old save. I created my own logos and put them in manual through Team Info tab in game. I know where the file is with all images but when I go to paste them over my new save they always revert back to the generic helmets, logos. jersey etc.. ( Leagues-HTML-images-Logos ) Its the same # of teams same format as previous safe? Just looking for advice on why it goes back to generic team images
