Google search console 404s with whislist parameter

Hi,
Google Search Console is showing a lot of 404s error of this type http://www.mywebsite.com/product/oceanik-mask/?add_to_wishlist=4408

If you follow the link, yes it shows my 404 page. But why this page is linked from http://www.mywebsite.com/product/oceanik-mask/?

Thank you!
