Alternative position view doesn't print to PDF

I have a drawing with multiple sheets and on two of the sheets I have an alternative position view.

When I print to pdf, or save to pdf, on of the views does not show the alternative view but the other one does.

The picture below shows the sides to the chassis in an alternative view and will print to a hard copy fine, but they disappear when I print/save to PDF. I have tried to set the quality to the highest and many other options. Anyone else have this problem?
