Theme style issue

Hi, I have added the free version on the website: now the content or the article number and all other info is half a page below as it was before I added the button. (I also tried only the text version of the button). Is the size of the button an option in the paid version or is there a trick so the contact will remain with each other in a correct layout? Kind regards, Roelof
