Button also shown in author box

Hi there,

odd things happening. In the new theme that I use, the buttons are also shown in the author’s box below the post.

See here to check what I mean:

Any idea of how to get rid of it? Or is it because I allowed WP to make the user profile shortcode-capable? What can I do?

Thanks in advance
