Typing the word "Contact" is creating hyperlinks

Hi all, this is my first post.

I have just noticed whenever I type the word ‘contact‘ in any new post, it automatically sets up a hyperlink to my contact form for on the site:

https://www.mysiteexample.com/contact

I can’t for the life of me work out how to stop this.

I’ve tried to highlight the words ‘contact‘ and ensure they are not hyperlinked, but whenever I save the change it still continues to do this.

Can someone please advise how to stop this?

Cheers
