removing header post links

On all my website posts there are either one or two links in the header that lead to posts on the site.

I’m trying to delete these post links but can’t find where they originate. I didn’t build this website. I had someone do it for me years ago.

Probably some code somewhere. I did see that there were specific plugins that remove items from header, but not sure if it pertains to this problem.

my website is http://www.Ironstruck.com. Here is a post that shows two links in the header ….https://ironstruck.com/triathlon-sunglasses-2/

Thanks in advance.
