Color dropping out when exporting from InDesign to PDF on a Mac

Hi everyone,

Maybe you can help with this problem. I'm using a khaki color (PMS 614) in InDesign in a few places throughout a document. It renders (i.e., is visable) in all places except one -- the footer. Why would a color export correctly on one page and not show up at all on another? Here's an example of what I'm seeing.

The first image (jpg) is the page in InDesign with the khaki colored footer in place and visible at the bottom.

The second image (exported to a PDF from InDesign) is the same page and the colored footer is not showing up. When I check Edit PDF in Acrobat, the shapes that make up this color border (a rectangle and turned square) are there in the PDF. Why aren't these shapes filled with PMS 614?

The only thing I know is different within the InDesign file is that this border is on master pages, not the individual pages of the document. There are pages with this color on actual pages (not masters) and they are visible in the PDF (see the cover & title page). But I've never had a color disappear because it's location in InDesign is on a master page. Any idea why this is happening? It's a first for me. I've exported to a PDF for print and interactive and neither will render the PMS color.

I'm using the most recent version (19.3) of InDesign. The exported PDF and InDesign files are attached for your review. Thanks for your thoughts.
