WordPress is self-replicating?

A website I am working on http://hessverdon.com seems to be self replicating. Examples below.

Those are all 3 different URL’s and there are 47 more just for this one page alone. There are over 1,500 total that we are seeing.

Does anyone have any idea what is going on here and how to fix it?
