I have a link that I can't get rid of or see in the code

On my website page, https://www.tranquilityzone.co.uk/courses.html I have getting a weblink to index.html when I view the bottom part of the page. For example there is a link in the page to another page from the word workshop, the first one works as I would like the second one sends to index.html even though the code link is to a different page.
At the footer of the page there should be page links but again the whole region sends to the index page.

Is this something related to the CSS code or something else?

Any help appreciated as I have no idea what is causing this on this and some of the other areas of the page.
