Bring to front/back options?

Hello,

Every time I save my drawings to PDF, my Hatch/Fill seems to dominate all other drawings and brought to front.

The following image is an example of what I mean:

As you can see, on the right side Solidworks shows two lines crossing the rectangle gray Fill.

However, when I save the drawing to PDF, on the left side, the gray Fill is the only thing shown; no outlines, no lines, no nothing!

I am wondering if this has something to do with layers...

What do I do to make sure that PDF is saved the way I see it in Solidworks?

Thank you!
