PDFs Formatted for Ingramspark Print Books Don't Work for eBooks

For print books, Ingramspark requires a .25-inch margin on the inside of the page where it’s attached to the spine. As an experiment I imported the print PDF into Kindle Create to get an idea of how the images are being exported. As expected, the portion of the image in the bleed area was removed. The inner margin, however, was not removed. When I eventually create the PDF for the eBook version, I’ll change inDesign settings to remove that margin.
