why does my published page look different than my design in site builder?

On one of my pages, my pin-it buttons appear in site builder to be where they are supposed to be, but they show up way down below the footer in the published page.  ( http://www.aboriginalartsllc.com/womens-sun-visor-viseras-1.html).  Also, I have a paypal button inserted as an html element on the top, right side of the top-most image on this page, but it does not show on the published page?  Why the stray pin-it buttons on the printed page, and why not my pay pal button?
