Preview display problems...

I have created a document with some text and graphics in Pages. I need to export and save the document as a PDF, as I have done in the past for printing, sending, etc. One of the attributes of the document is "outlined text," created by highlighting the text in pages, and selecting outline from the "advanced options" menu (the gear button).

(I've placed a text box that contains the outlined text directly over a text box containing the same text, except solid in a different color to create a layered effect...not important.)

When I open the document as a PDF, everything appears identically to the pages file EXCEPT this outlined text. The outline is almost entirely missing.

Here's where it gets interesting...when I print the document from that PDF with missing outline text, it appears in the print. When I open it with Preview on another computer, (same OS), it's there. When I export that PDF with the missing outline to JPEG, PNG, TIFF, it's there. I've tried deleting the preview containers folder located in libraries which did not help.

Any help would be greatly appreciated! Thank you.
