Edit Cover without changing underlying page

#1

I am new to Prezi and struggling a bit with editing Topic Covers and Pages. I am trying to make the border and primary topic circle on the topic page completely invisible using opacity, but I want the border to remain on the overview page. Every time I edit it in one place it changes in the other as well. How can I edit on the topic page without impacting the overview page?
