Getting rid of a link on a product

Site URL: https://bluebonnetstudio.com/kits-and-accessories/tekobari

Our website has a link on each product that transfers the user to a specific page.  This is a legacy feature implemented many years ago previous to the new editor.  I can not find any way to edit the link and its text or simply to delete the link.  A picture showing the link is provided.  Does anyone know how to edit the link and/or how to delete it.

Thanks!

The "Back to" link is a standard feature on the Devlin template that you're using. Do you want to hide it or repurpose it?

Yes I wish to hide it.

I also might want to repurpose it.

Thank you tuanphan!  I learned a bit more by this change.
