Hi,
The screenshot I gave is also from the cart display you can choose as a menu, and not the cart on the checkout.
So that makes sense yes, we're talking about the same page 
Then, besides a view override in your template, I don't see any other reason.
Try to switch to the default template of Joomla temporarily and see if you have the issue.
If you don't, then it's definitely a view override of the template, but maybe not the point I was pointing out but another one. In that case, you'll have to check the other view files / folders in your template's com_hikashop folder.
If you do, then I don't know what's going on and we'll need a backend access to your website to be able to check on the situation as well as precise instructions to reproduce the issue on the frontend. In that case, you can provide the information via our contact form along with a link to this thread for reference:
