Can’t find Bad URL

Hi –
On the homepage of my company site, [ redundant link removed ], there is a revolving slider. When you click on the client testimonials side of that slider, you are taken to a faulty link:

/testimonials/client-testimonial-2

However, I cannot figure out where that link is to remove it? I have checked the settings of my slider widget, I have checked the images stored in my media, and I have used chrome dev tools to find it and have been unable to.
I was wondering if anyone could please take a look and point me in the right direction?
Thanks,
Megan
