Appointment Blue missing

Website is sydney-tours.com.au

Am having a problem with W3C validation. Can you please tell me where the following is stored.

This is an example from https://www.sydney-tours.com.au/wild-kangaroos/

							<h3><a href="https://www.sydney-tours.com.au/wild-kangaroos/">Wild Kangaroos</a></h3>

It is missing a before the </div> that appears before the <h3> towards the bottom of the code.

Any ideas as to where this is stored so that it can be repaired would be appreciated.

Thanks
