Mood Board save to PDF output issue

I create my mood boards with paint colors from the paint library included. I crop the paint colors to a circle shape. The issue is that when I select "Download Client Presentation (PDF)" AND select to "Hide the Presentation Header", the circle shapes turn to ovals and the text is not as clear as on screen.
I can select to download PDF and NOT hide the presentation header, however, it makes the presentation too small as the header takes up so much space. I have this issue no matter what browser I use. I have tried clearing the browser cache and that has not fixed the issue either.
