Why are there Grid Lines with Publishing to PDF from CorelDRAW X6

I opened a Corel X3 document.   I worked with it in Corel X6.

I saved it back down to X3 and when publishing to PDF, I opened the PDF

And nice, ALL KINDS of really weird, and Lame Grid Lines

And I dont know Macros.  Why do I need to learn Macros to remove these Grid Lines

Any solutions for this funky issue with awesome CorelDRAW X6?
