Do not show shariff buttons in overview page

Hello,
today I installed shariff and I am very excited to use it. Unless my website is still under construction I may just explain my issue.
I have choosen to show the shariff buttons under the posts. For many post items I use an overview to be shown with “READ MORE…” In thjat overview, the buttons are shown and that is disturbing. How can I switch that off?

The page I need help with: [log in to see the link]
