Remove part of bio

Hi, love this theme best I ever had. I have only one question: beneath each post there is this line “view all posts by author xxx”. And the problem is that I use the User Post option. This means that people can create their own posts. But then it shows “view all posts by author blah” and if you click on that it shows all posts by authors that used the user post option. Not just the posts by author blah.

So I would like to either remove that line, but I don’t know how, and would like to know, or I would like not to show that line with certain author.

Can you please tell me how to do one of these?

Thanks
