AddToAny shows YARPP posts for Pinterest

We are using Yet Another Related Posts Plugin (YARPP) to show related posts on our post pages. We also are using AddToAny on our posts. When I click on the Pinterest button from AddToAny, it not only offers the option of sharing the particular post, but also shows all the related posts as options. We only want to show the current post. Is this behavior by design or a bug?
