Duplicated Content on One Page

I’m using a Twenty Seventeen child theme for this site.

I created a series of six html/css buttons for a page and pasted them on the problem page identified below. When I viewed the page, there were two sets of buttons. While troubleshooting the problem, I created another page with just one button to see what would happen. When it displayed properly, I added more buttons until all six buttons were present – the code is identical to that of the problem page. I then returned to the problem page and removed one button. Now the top of the page shows five buttons but the bottom still shows the original six buttons.

Can anyone suggest what is happening here?

Thanks!
