@Harleigh Manske I'm sorry this is a long message, I made another post about this online recently and these were comments people said about this: -If you have full bleed color on most of your pages but those last two pages have a white border, the KDP algorithm can mistakenly flag that as a mistake. You can fix it by changing the “color” on those white pages to a slightly off white and still retain your design aesthetic. -If you select "my book has bleed" in the KDP setup settings, you need to add .125 inches to each of the outside edges of the book (not the interior edges that touch the spine) So an 8.5x8.5" book, laid out as a spread, is 8.5"x17. In your formatting software, Add 0.25 to each of those numbers which will add 0.125" to each side edge and the top/bottom edge. -KDP isn’t spreads, they’ll reject it if it’s not individual pages. So, 8.5” square pages would be 8.75” high but only 8.625” wide to have bleed only on the outer edge. -You still need to print it as individual pages -print in individual pages for KDP -It may not be bleed—you’ll also get this message if you have any images or text that end close to the edge but not fully over the bleed zone. -If the rest of the book has bleed, it's possible that you didn't extend the artwork box far enough. If you are using Canva for example, and all other pages with bleed are fine, go into Canva and zoom in really close and look around all of the perimeter of the page to see. Sometimes you might think something snaps to the end but it might not be. -Also if your illustrations have any line work that could be misconstrued as text it will flag it too -Sometimes if you compile pages in a PDF editor then some pages might have bleed and others might not. -Make sure your images/backgrounds extend 0.125” beyond the edges (bleed area) on those pages. Use the correct KDP template and export as PDF with bleed that usually fixes it.
