'BACK TO' link on products page

Site URL: http://www.impelo.org.uk

Hi folks, I've set up a range of products via the commerce section on my site: https://www.impelo.org.uk/impelo-dance-classes

I've opted to design the page and insert the desired products myself, as I prefer the design that way. My issue is that once inside a product page, there's a link that appears in the top left corner saying BACK TO CLASSES, which currently links to an unwanted classes page. I'd like this link to either direct back to: https://www.impelo.org.uk/impelo-dance-classes or just not be there at all.

Many thanks,

I've found the problem - there was code injected to the page:

<a href="/dance-classes">BACK TO CLASSES</a>

All sorted now!
