Posts redirecting to similarly-named posts once clicked…

I am not sure if this is a Genesis issue or a wordpress issue but I have searched both forums and found no answer that helps.

I am having some posts thumbnails directing to wrong pages. In the page (https://my-how-to-draw.com.izela.com.au/how-to-draw-spiderman.html) you will find that 2 of the 3 posts (excluding spiderman 2099) go to the wrong post.

The link address is correct but it redirects once clicked for some reason. It goes to a page with a similar name so I am thinking this may have something to do with it but it is still a problem that I need to fix.

Thanks,
Emmanuel
