Fix KDP Paperback Cover PDF

I have a 6" x 9" paperback cover PDF that Kindle Direct Publishing keeps rejecting. The platform either refuses to open the file for preview or immediately flags it for “incorrect dimensions.” The artwork itself is finished—I only need the file rebuilt and packaged so it passes KDP’s automated checks and is ready for print.

You’ll start from my existing PDF (plus any source files you might request) and return:
• A print-ready PDF that uploads without errors to KDP and displays correctly in the previewer
• A brief note outlining the exact specs you used—trim size, spine width, bleed, and color profile—so I can replicate the process next time

Please bid only if you have successfully prepared 6" x 9" paperback covers for KDP before and can turn this around quickly.

Here are two files that failed to upload ready for publication.
